JoJo no Kimyou na Bouken Part 3: Stardust Crusaders is one of the worst anime that has been made (in my opinion) for two main reasons, it is super repetitive and overhyped. For the repetitive part, I usually don't mind if an anime is repetitive by ARC because at least they add something new. One example is Alabasta Arc and Dressrosa Arc from One Piece. Both have the same formula of story but they have aspects that are unique to each other but here in Trash-I mean JoJo it is repetitive by EPISODE. They will encounter a Stand user that came out of nowhere, without proper build up. The main characters will fight them for 24 minutes, defeat them and that's it and the show does not even make it interesting. It's on par with ecchi/romance anime in terms of cringeness.
Naruto or Bleach fillers are more well written than this. Hametsu no Mars is way more entertaining than this. A generic isekai is way more refreshing than this. The only reason to watch this anime is for the memes. Other than that it is an utter waste of precious time.
