OP songs were catchy.
I like that detail with Ed's shirt collar changing through timeskips
Trisha Homunculus was hot
Generic shonen shit spread across 3x too many episodes. Incredibly redundant themes and whiny main character. "I'm gonna get my body back! Gotta remember that! Life is sacred!" Not bad but very mediocre.
Literally everything. Though the most important part is that it ended where it was supposed to and didn't get dragged out and thus turned to shit for 400 more chapters like so many other series like Naruto, Bleach, etc.
