It's also extremely intense and downright unpleasant to watch for much of its runtime. Also body horror, so much extremely intense body horror.
I don't mean to put you off watching it, it's very well-done, quite a good series if you enjoy that sort of thing, but it was too much for me, especially the body horror!
So yeah, beware, but that doesn't mean it isn't good, it is very good, it's just also intense and gross and uncomfortable
