Talking about FMAB, it has freakin' 64 episodes! One needs to dedicate some time for it in a relatively passionate way in order to watch it from start to finish, so I don't blame you at all. Not even mentioning neverending titans like One Piece, though I don't deny I'll start watching it again someday in my life simply because why not
Neon Genesis Evangelion has 24 episodes and that sounds very, very reasonable to me. There are continuations of it, luckily, because I didn't think I would get to love the show so much. (That's why short animes are a plus in my book, it's simply "fast" to get to know and see what stuff is about).
Other than that, I don't even want to think about all the animes on my watchlist that I ignore since 9th grade. SINCE 9TH GRADE. I guess me watching a new anime is like a miracle that I don't know how to trigger, but I find myself in it from time to time lol
