I knew in advance that this was supposedly a good one, but the first episode really disappointed me. Barbara was behaving completely out of character, Ian was being a bit useless, and the cliffhanger involved the baddy turning *directly to camera* to outline all his evil plans.
Luckily, it picked right up from episode two onwards, with Barbara and The Doctor getting into some proper debates about the nature of time travel, the story becoming a lot more intriguing, and Ian taking a level in badass that would (though I didn’t know so at the time) remain in place for the rest of his journey.
The best thing, though, was The Doctor’s bit of comedy business with the randy old woman in the garden. The hot chocolate thing made me laugh for ages.
