Season 4
USS Callister
What a way to start. This is the series at its best, attacking hostile nerd culture entitlement this time with the series typical cutting humor and clever storytelling. A great cast, featuring a fearsome no B.S. performance by Cristin Milioti, Jesse Plemons ability to transform into the type of person the story needs him to be at any moment and Jimmi Simpson, who is always a delight. One of the best endings for a Black Mirror ep, which is saying a lot.
Arkangel
The final moments and closing credits song made me think this was going for something else. The relationship between mother and daughter doesn't connect because the script spends more time interacting with the technology and not enough dealing with the human consequences. This was the first in a sad trend this season, being able to easily guess where and how the tech is going to go wrong.
Crocodile
If you didn't like the darkness of last season's "Shut Up and Dance", you might want to skip this one. At least Dance packed a punch with its final scenes. This one, I kept waiting for a surprise and instead I was unsurprised when a sociopathic solution presented itself and it went there. This could've really used a twist.
Hang the DJ
I don't want to say too much on this one because its those final minutes that really put it over the top while a good deal of the middle I thought was setting up something darker. If you liked San Junipero, this is another look at the danger of turning over our dating instincts to new technology.
Metalhead
I'm not sure what the point of this was. I mean, I get the point of the final scene, but the rest of the episode is a low tech version of The Terminator. The shortest episode, but so lacking in content it felt the longest.
Black Museum
Curious structure. A crime museum where the owner tells stories of tech gone wrong. The first two-thirds could stand as their own episodes if the show ever went to 30 minutes. Only in the final tale does it lead somewhere, but again as soon as that one began and I know exactly how it was going to end.
