USS Callister ("stealing my pussy is a fucking red line" is my favourite quote of the series and Nanette works fantastically as the protagonist. I went into it expecting more-or-less a straightforward Star Trek homage, which didn't interest me much, but by the end I absolutely loved it)
Hang the DJ (the noise that Lenny makes after... ahem, tending to Amy's nether regions is my second favourite quote of the series. Just a cute episode, and I liked how the 99.8% thing was all tied up at the end)
Crocodile (I really, really enjoyed this episode for all its bleakness, up until where she kills Shazia, where it just becomes torture porn [killing the blind baby was waaaay too far], and I felt like the ending itself could have been a lot stronger. But as I said, I thought most of the episode was great, and I liked the whole researching-into-a-collision-with-a-pizza-van-for-insurance-purposes-turns-into-accidental-discovery-of-a-murderer type thing)
Black Museum (Jack's new girlfriend pinning a toy monkey up against the wall and repeatedly swearing at it was joyous [though probably not for the toy monkey, I'm guessing] and I thought the last ten minutes or so were brilliant, if not slightly on-the-nose in its attempt to be woke. However, I hated the first story, and I'm really not sure why they decided to copy the structure of White bloody Christmas of all episodes)
Metalhead (I get what they were going for here and I do think that they did it well, but post-apocalyptic horror just isn't really my cup of tea, and I ended up wishing that the dog had caught her a lot sooner to get the whole thing over and done with)
Arkangel (meh. None of the characters were likeable, the story was bland and predictable, and I was left with a sense of apathy at the end rather than catharsis. Also, Rosemarie Dewitt didn't age a single day and that really freaks me out)
