The Sea Devils

I really can't fault 'The Sea Devils'. Well all right, apart from the incidental music, which is almost supernaturally irritating, I can't fault 'The Sea Devils'. Great monsters, superb characterisation, and perhaps my favourite use of the Doctor's arch-enemy, add up to make something of a classic. 

First off, the Doctor/Master rivalry is marvelous here. I've charted the progress of their relationship over the course of Season Eight in previous reviews, and I've noticed that most of the time the Doctor has very little regard for the Master, whereas the Master seems to respect the Doctor far more and is desperate to impress him. This seemed to change somewhat after the Doctor's refusal of a half-share in the Universe in 'Colony in Space', and this is evident here; the Master is far more ready to actually kill the Doctor here (rather than finding excuses not to do so), first throwing a knife at his back with a genuinely murderous look on his face, and later in episode six urging the Sea Devil leader to kill him. Despite this, his respect for the Doctor's intellect is once again on display, as he forces the Doctor to help him build a device to wake up the Sea Devils. As in 'The Mind of Evil', the Master seems to rather enjoy this brief collaboration. On the other hand, the Doctor's attitude towards the Master seems to have mellowed slightly, since his enemy has been imprisoned by UNIT and possibly because he is thus trapped on Earth just like the Doctor. Although the sunken ships arouse his curiosity, and although he seems to want to get his hands on the Master's TARDIS, he does nevertheless admit to Jo that he feels sorry for the Master, and that they used to be friends, the first time this is actually confirmed. 

The Master is both at his most charismatic and most ruthless here, exhibiting his considerable avuncular charm when in conversation with the Doctor and Jo or even Trenchard, but eager to start a war purely out of malice and a desire to avenge himself on the human race for locking him up. Delgado puts in an especially good performance, effortless switching from charm to fury in an instant; of particular note is the scene in episode six, when the Sea Devils attacking the base are defeated and he is briefly held prisoner in the Naval storeroom whilst the Doctor goes to check on Jo. Earlier, he attacked a petty officer when caught stealing equipment, but whereas there he did so casually and without obvious emotion, here he lashes out in fury, raising his voice as he does so, Delgado giving us a brief glimpse of just how frustrated he really is that his plans have briefly been derailed. The whole story is full of great Master scenes, including his sword-fight with the Doctor, him being saluted by sailors whilst he poses as an officer, and his wave goodbye to the Doctor as he escapes in the hovercraft during the final scene. 

Pertwee, for his part, puts in a very good performance as the Doctor. He is just as good as Delgado in his scenes with the Master, and helps to make their sword-fight a highlight of the story. The Doctor is generally at his eccentric, egocentric best here, gallantly diving onto barbed wire so that Jo can cross it without injury, guilelessly stealing her sandwiches later on, assuring an attacking and obviously hostile Sea Devil that he won't harm him in episode two, handling Walker in episode five, and briefly convincing the Sea Devil leader to consider peace despite the interference of the Master. In addition, the Doctor gets to pilot a speedboat and a ski-jet, and take a trip in a diving bell (rather smugly responding to Hart's question as to whether he's an experienced diver or not with the answer "Naturally!"). He also turns a transistor radio into a transmitter (in the process demonstrating that he isn't infallible, since it first doesn't work and then explodes after he's used it, in a nice moment of comic relief) and even gets to reverse the polarity of the neutron flow. In short, he's at his most capable, heroic best. That said, points are deducted for him falling for the Master's fake collapse routine in the hovercraft, although being taken in by such an obvious ruse would explain why he looks so frustrated in the very last scene (incidentally, when did the Master get the chance to obtain that mask? Surely he didn't have it in prison…). Jo also does well here, rescuing the Doctor in episode three and again in episode six (well, almost - he rescues himself, but at least she makes the effort), and standing up to Walker.

The Sea Devils themselves look rather good, despite their static eyes. I rather like them actually; although only one of them speaks (their leader), he comes across as a rather noble sort, certainly more prepared to listen to reason than Walker when it comes to discussing peace. It makes me wonder what the Doctor might have achieved had the Master not got involved. In addition, despite having less to say than their cousins in 'Doctor Who and the Silurians', the actors playing them manage to convey subtle characterisation, especially the Sea Devil guard in the submarine, who watches the captive sailors with curiosity as they play cards. As in 'Doctor Who and the Silurians', the tragedy of the situation is that both reptiles and humans have a right to the planet, but both make a peaceful solution difficult at best, the former sinking ships and killing their crews, the latter retaliating automatically and foiling the Doctor's hopes of a peaceful solution. The actions of both sides are understandable, which only adds to the tragedy.

The characterisation is generally superb, a trademark of Malcolm Hulke's scripts. Captain Hart is a stand-in for the Brigadier, displaying none of the unfortunate buffoonery inflicted on Lethbridge-Stewart by the production team of this era. His exasperation at the Doctor and later growing respect for him are very familiar and work very well, thanks to Edwin Richfield's acting. The pompous and boring but ultimately well-intentioned Colonel Trenchard is played to perfection by Clive Morton. His naivetй and indeed stupidity in dealing with the Master make raise the question of whether he was told anything about his prisoner but at least his heart is in the right place, even if his brain isn't. The scene in which he believes that the Master thinks the Clangers are extra-terrestrials rather than puppets, to the Master's obvious exasperation, nicely highlights Trenchard's lack of imagination and gullibility. And his death has a certain stout nobility to it, as he determinedly guards his prisoner to the last. The other supporting character of note is Martin Boddey's Parliamentary Private Secretary Walker, one of the most genuinely loathsome characters ever to appear in the series. Stupid, arrogant, patronizing, self-opinionated, and willing to exercise the powers unwisely granted to him with any regard whatsoever for the consequences (he seriously considers nuclear strikes off the English shoreline), he is thoroughly dislikable, and this makes the Doctor's verbal dressing down of the man and his later exposure as an abject coward all the more gratifying. 

The direction is excellent. There are some marvellous set pieces, especially on board the sea fort, which boasts some highly suspenseful scenes. Sets and model work throughout look highly effective, but most notable is the extensive filmed location work, plus footage of the navy, which integrates very well and makes the entire story seem impressively lavish. The use of the navy is part of the reason that I like 'The Sea Devils' so much I think; they serve the same purpose as UNIT, but lack the twee coziness that genuinely grates on my nerves by this point in the series and aren't blighted by Mike Yates. Overall, 'The Sea Devils' maintains the high quality of the season thus far, a quality that sadly starts to decline with the next story.
