Bad Wolf
After the somewhat dismal Boom Town (which seemed to me a filler that was merely meant to set up the cracking finale) I figured that Bad Wolf would almost have to be an improvement--which it was, but after a second viewing I'm still not quite sold on the lampooning of reality TV. It just seems to me that a fad in the 20th C. wouldn't have continued that long into the future, even if there is a progression towards "killing" the people who are "kicked off the island" so to speak, I think that "reality" TV would burn out very quickly before any such point was reached. (Think of the use of the zombies in game shows in the ending of Shaun of the Dead, for example, as a parody that seems more in the realm of possibility, IMO, despite the fact that they're bloody zombies).
Now, of course, this is Doctor Who, and there has always been a need to suspend disbelief at times that exceeds most other shows. So considering this entire Season (series for the UK folks) of Doctor Who, and the over-tendency to reference current events, Bad Wolf performed as expected, but that still doesn't mean we all have to like it. It's too close to home, or too obviously close to home, and even more than the Pertwee era, lacks subtlety in referencing current events.
Overall, Bad Wolf seemed again, a little too much like a setup, and it seems Boom Town was a wasted story. The setup of Bad Wolf could've been there, and that would've have left two episodes to deal with the Daleks. I am far from a Doctor Who purist, but I think the main shortcoming of the new program has to do with 45 minutes not being enough to tell a story, so we're stuck with overflow material being collected into a bucket and presented as Boom Town, instead of a fully realized story.
