'Terror of the Autons' was fun but flawed. The Master lays a series of schemes within schemes and traps within traps for The Doctor like a blueprint for the Batman/Joker tussle in TDK.
Having read a lot of Sherlock, I most enjoyed the three way Holmes/Watson/Moriaty dynamic that the writers had deliberately developed for The Doctor/The Brigadier/The Master in episode 3. And the seeing the first scenes between The Doctor and The Master was great. The Doctor's almost petulant irritation when The Master is first mentioned by a third Timelord was lovely. I like moments when we are reminded that despite the character's and the actor's age he is something of a rebellious teenager in Timelord terms. At one point when things aren't going his way Pertwee remarks...
"What's wrong with being childish... I like being childish"
...and has a bit of a sulk. It's one of the unique things about the character.
Onto the bad. New companion Joe is very weak and flimsy here and in a funny scene The Doctor tries to have her fired from UNIT. She obviously gets more serious later on, as she seemed totally different to the Joe from the later 'Sea Devils' and 'Day of the Daleks' serials. But the worst thing is the experimental Chroma-Key video effects. They are so bad that at times they don't just look unrealistic, they verge on the psychedelic. They are used in almost every scene, even when they don't need to be to create 'virtual sets'. I'm not sure if this is down to limited budget, an air of free experimentation of just not giving a shit. I supect it's a little of all three but whatever the reason, it's very strange. Hopefully it doesn't get used this often in many other Pertwee shows.
^ This looks pretty bad as a still (And this is one of the better shots) but in motion when the foreground and background are moving slighty out of time it's something else. And finally the ending is awful as after the thrilling cat-and-mouse games run out of steam The Master just gives in after one sentence from The Doctor. Still overall a good four episodes.
Time for some Peter Davison and Tom Baker before I watch more Pertwee I think.
