“The ending of that was like half the episode,” our son grumbled. And no, the ending is about two minutes long, but it’s sentimental and emotional enough to drive a young viewer nuts. I think that until the end, he was enjoying this time-travel adventure much, much more than anything since the pirate story, and he’s just letting himself get extra-aggravated by people crying and saying they love each other. Karen Gillan is really, really good in this. It’s possibly her best performance in the series.
