Yeah, you're right - just saying it was 'too soon' after his departure does seem like an oversimplification. From what I've read, Tom Baker was pretty burned out by the end of his run as the Fourth Doctor and was hesitant to return so soon. There?s also the fact that he?s always been a bit unpredictable when it comes to Doctor Who appearances. He?s even said in interviews that he didn?t want to do The Five Doctors because it didn?t feel like the right time for him personally.
