I honestly should probably post in there, but based on previous threads I've seen, something always seems to happen in OTs relating to anime (like One Punch Man's OT just going ballistic over ONE FRAME from an episode resulting in pages & pages of people arguing) that kind of turns me off from them. & for Jojo Part 4, considering I've already read it, I don't want to turn into one of those "oh man can't wait for THIS moment to be animated" since that was a huge problem for Part 3.5 eps in and my mob psycho OT only has 390 posts. my OPM OT had over 1000 at that point, and over 10,000 when the show was done, so it blew up.
MP100 doesn't have an immediate hook like OPM. Also not about superheroes and fighting so will be less popular in the West
