Made in Abyss
EXTREME violence & body-horror in a series with a child protagonist. While season 1 had it’s share of disturbing scenes it didn’t necessarily seem gratuitous (to me) for the story. If you’ve watched many nature documentaries you realize how violent & brutal it can be. Likewise how disgusting biological functions are if you’ve watched any reality medical shows on cable. However, the longer it goes (the sequel movie & 2nd season)the more it can feel (to me) like it’s just trying to outdo itself & certain things almost feel fetishized. To use @Daxter’s “was it worth it” analogy, season 1 was yes for me but beyond that point it’s questionable & think I’ve probably reached the limit on my tolerance.
Also most of Junji Ito’s work that I’ve read/watched. Frequently called a Master of Japanese Horror, I admit to him having a knack for being weird & disgusting, but rarely what I consider “scary”.
