I'd love to stay up and write a reaction post for this story, but it's on too late considering I've got work in the morning, dark and early. So just going to point at this and say, "Hey, y'all, good classic Who on TV tonight! Get some."
Pertwee, as I recall, is genuinely funny and brilliant after recovering from his regeneration. His Doctor gets compared to Bond, another British icon celebrating its 50th anniversary, but it's not really fair. Pertwee, while more ready for action than a Doctor before or since, isn't exactly a Bond, and Bessie is no Aston-Martin -- though the Whomobile (not in this story) is nifty and daft. If you come to this story new, expecting a Bond-type action thriller, you're going to be disappointed, but if you expect just a bit more fisticuffs than you've seen in other Whos, and a Doctor who's a bit more Steed than Bond, I think you'll be in the right frame of mind.
