Day 383: Robot Part 2

Tom Baker is the Doctor. It's actually shocking to see how both how quickly he is able to settle into the character of the Doctor and how quickly his characterisation of the Fourth Doctor forms. He is a bit erratic, a bit wild, and instantly more fun than the more stoic Pertwee. And we can see all of this within his first episode. This is in part due to the way in which Terrance Dicks, the writer, has written him. But it's also in part due to the performance of Tom Baker, who is able to instantly prove to audiences that he is the Doctor, and the series will never be the same again.
