I think this episode is without doubt the episode everyone has been waiting for since the series started, even before. It doesn't matter whether your a fan of the show or not, watched the original or not, because there's not many who haven't heard about the daleks. Even those who are too young to remember the original series have heard about the Daleks, so expectations for this episode were high.

The episode opened with a cameo from another of the Doctor's biggest and famous of enemies-the Cybermen. Luckily enough for the casual viewer the quick climpse wasn't laboured and full with remarks to previous encounters between TimeLord and Machine. Had this been the case many would have soon turned off put off by the constant remarks to events they know nothing off. Luckily the sequence was quickly over and the Doctor was arrested.

He was quickly introduced to the second villian of the piece, an american billioniare who collects alien artifacts. He wasn't the best of characters to be honest. Whether that was due to poor scripting or acting its difficult to tell but he didn't shine out, he just felt like a plot device to introduce the audience and the Doctor the main enemy of the episode-The Dalek. The Doctor stroded agrogantly into the cage expecting he could help the alien and expecting the alien to be greatful of his help. The last thing he expected to see was his arch rival hidden in the dark and the horror on the Doctor's face was plain to see.

The episode quickly picked up some much needed pace so it could be all over and done with in 45 minutes because of the restrictive new format. This episode could have done with being a two-partner to allow events to be spread out instead of feeling rushed. The deaths could have had more of am impact if the Dalek chasing through the corridors was expanded. It slowly hunting down and killing its captors. We could have seen the fear, horror and tension from the other characters as they fought for their lives and the realisation that there's a better killing machine other than mankind. All these themes and others could have been explored more deeply but let it not be said that this was an excellent episode.

The influence of the new Battlestar Galactica could be felt here. The enemies in that series were once chrome robots who hunted down mankind because they had no other purpose. But the new Cylons are humanoid and have emotions, they have evolved and because of it you feel for them. Their are times when you are on their side or at least you understand their motives. This episode had examples of that. The Dalek, by using Rose's DNA to regenerate, developed emotions as a side effect and by doing so the audience began to feel for it. You sympathised with it, more so than with the Doctor. The Dalek was the last survivor of its race and all it could do was follow long programmed orders to kill but desperately wanted new ones. Meanwhile the Doctor almost became the villian of the piece through his determination to kill without listening to reason or letting emotion come in the way. Even the Dalek pointing out the Doctor was acting more like his species than Timelords didn't really stop the Doctor. It took Rose and the mutating Dalek begging to be killed for the Doctor to realise what he had become.

The episode also confirmed my suspsion that the Daleks were invovled with the great timewar and also hinted that if a Dalek survived other Timelords may survive as well.

Once again Billie Piper stole the show with brilliant acting and the supporting cast were better than some so far although perhaps not as brilliant as one was hoping. Christopher Eccelston improved on previous performaces as the Doctor but he still doesn't quiet feel like the Timelord I have come to know and love thanks to UkGold repeats, VHS and DVD releases due to being too young to remember the original series. This episode gives me hope for future episodes after previous ones failed to engaged or to impress me, bar Wolrd War Three that is.

Well this was it. This was what the fate of the entire series was resting on. Seems a bit odd that they kept it back to episode six frankly, especially after the abysmal effort that was episodes four and five. (I'm so ashamed I can't even refer to them by name any more).

The Daleks are definitely back. Bigger, badder, bolder and bronzer than even Kilroy-Silk. Let's get one thing out of the way. In order to help itself regenerate it needed "time traveller DNA", though how Rose's DNA would have been changed by time travel is a mystery to me. The Dalek knew it needed this but seemed surprised when it, apologies for substituting one dastardly tag line here for another, assimiliated Rose, and got all sorts of girlie thoughts in there as well. For heaven's sake! The bloody thing had assimilated the entire internet. Did it just skim over the websites for Hello! magazine and Top Shop? Frankly if I were looking for aliens on Earth, I'd probably start with Hello! magazine.

I definitely approve of the upgrades and it seems the Mill have finally sorted themselves out with the special effects, and are producing effects, not only that the series deserves, but that viewers want to see.

It was frankly a single premise story but it was very interesting to note the helicopter at the beginning of the episode was referred to as "Bad Wolf" and now with the Grafitti from last week and episode twelve, another big Dalek one, also being called "Bad Wolf" I know this is going to turn into something interesting, and I hope they manage to keep it a secret until the time is right.

It was good to hear more about the time war. frankly anybody with a brain could have figured out it was the Daleks' fault. I sincerely hope they don't just keep referring to it however, and actually show us either it, or some refugees and consequences of it. It's a bit like hearing about Somalia on the radio but never seeing the full horror of it for yourself on TV.

So there you go, my review. I liked it... alot! It was precisely what I've been waiting for and was in my opinion the strongest episode so far. Cool to see a girl from Stargate in it too, never hurts!

Once again, the work of a different writer marks a much welcome change of tone and pace for the show.

There were huge expectations for 'Dalek' - the return of the most celebrated of the Doctor's enemies, the middle-season event episode, the promise of a darker, more complex tale.

Incredibly, it delivered.

After the slightly goofy shakiness of 'Aliens of London' and 'World War Three', we were thrown straight into a tighter, more claustrophobic setting in the form of Henry Van Statten's UFO museum, deep in a bunker in Utah. The Doctor and Rose are catapulted into the tale within the first five minutes (after a rather wonderful fan-pleasing moment featuring a Slitheen arm and - brilliantly - the helmet from a classic series Cyberman), giving us over to the episode's real star - the Dalek itself.

There has been huge build-up to this moment - the Doctor's vague references to the Time War which wiped out the Time Lords and was responsible for countless further damage to the Nestenes and Gelth, amongst countless others, have clearly been related to the Daleks.

And the creature's unveling, followed by the Doctor's gobsmacked reaction, which soon turns to venomous hatred, was outstanding. This was not a dumb, clumsy pepperpot which could only yell 'Exterminate', this was a soldier, intelligent, manipulative and incapable of understanding that there was nothing left for it to fight for.

Until, that is, it uses some of Rose's DNA to repower itself (a contrivance which seems sketchy but is entirely forgiveable given the places it takes the story) and sets about wiping out the inhabitants of the bunker.

There were so many superb moments here, not just Doctor Who moments but moments of real, heartfelt drama. Chris Ecclestone, after looking a little unsettled in the previous tale, dives into the script with a vigour and commitment which is entrancing to watch. Here is a Doctor who is not only eccentric and mercurial, he is damaged. He still hurts and hates for what happened to his people. Ecclestone's movement from fear to hatred to anguish to desperation to sympathy is an absolute joy.

Yet, almost unbelievably, it is once again Billie Piper who runs away with much of the episode. She has none of the Doctor's (or, indeed, many of the audience's) history with the Daleks, allowing her to see the wretchedness of its existence and to show it a second's kindness which ultimately saves all their lives and takes the viewer into the real tragedy behind the two races of aliens whose face-off she gets caught in.

Special mention should also go to Nicholas Briggs, who gives the Dalek more depth than any seen before.

It's hard to see how the series could get any better than this. Rob Shearman should certainly be given more episodes to write next season and I can only imagine what such a radical rethinking could do to, say, the Cybermen or The Master.

All this, and a new companion to boot. The Doctor has been back for a few weeks but now, finally, he's even better than before.

And just what is this recurring Bad Wolf reference leading to?
