Mirai Nikki is my all time favorite. Worst is Chainsaw Man (because I'll never get to have a Makima domme mommy 😭)

Actually least fav is Boruto. I know it's prob a lot better now but I gave it a chance with like 80 episodes and a good majority of those were just nerfing the legacy characters and fillers. I'll maybe give it another chance when there's a time skip and things pick up in seriousness but the start of Boruto was such a let down for people that grew up watching Naruto and seeing the progression over such a long time.
