Never seen human centipede, but it's been a while since I had such a visceral, stomach churning reaction to walrus metamorphosis torture, and I watch a lot of horror. Rewatched hereditary, enjoyed it even more, watched midsommar two nights ago, though I would say it's not entirely accurate/bitch is annoying at beginning, but that makes for the transformation plot, and don't trust jew directors motives, but loved the intricate detail. Don't get why that one has more mixed reviews though.
