Jojo's used to be one of my favorite animes/mangas, but I'm not that into it nowadays.

Personally, I find that the latest parts are the better ones and Araki surpasses himself. My favorite ones were 6-8! Even though I ended up dropping Jojolion pretty much just a few chapters before it finished, since I ended up losing interest (reading a chapter a month -without taking into account Araki's well deserved breaks!- wasn't really exciting for me, it made me had to reread chapters every month just to remember what was happening) but I still remember it very fondly.

I'm excited for the part 7 anime, though! I might watch it, even when I didn't watch the part 6 anime (though it seems I didn't lose on much)
