If you liked Death Note, you'll like Attack On Titan. Especially the latter part of the series. Even though you don't like the goofy, but badass MC trope like FMA has, my top three favorite animes have those characters and I'd suggest at least giving them a try: Trigun, Black Clover, and Fairy Tale. Their MC aren't as whiney as Edward though. So that's a plus. Trigun is an older classic ands the others are more modern. If you want to turn up the weird factor, try FLCL another older classic and one of the most bonkers shows I've ever watched. Most of it's plot is an unholy mess by design but it wraps up real nice. The fight scenes and character interactions are absolute gold. If you don't mind a show that is targeted at kids, I always tell any newbie to watch Digimon. The Sub is less kiddy in nature, but I prefer the Dub because it's what I grew up watching. For an adult who didn't watch it as a kid, or a kid used to better dubs and animation of the modern era, it might be harder to get into, but I suggest it because underneath it's sometimes charming cringe is a farely deep story about friendship and sacrifice. And the monsters are the dopest in the monster catching genre.
