Angel Beats seems to be in a weird spot for the audience of this poll. Aired nine years ago, wasn't on Toonami and is not a shounen. It's actually one of the most popular anime of the decade.
Watched this live in 2010 and thought it was a strong sentimental drama then. All of the characters are stuck in limbo for one reason or another and have to resolve a personal trauma to move on. But they start to form bonds with other lost souls making it hard for them (and the viewer) to seperate. I'll never forget the reveal of who Angel really was and how Otonashi died to begin with.
Angel Beats doesn't always try to depress the viewer though, a lot of it is objectively funny as it tries to inject comedic relief whenever it can. So you can experience a wide range of emotions throughout
Not totally sure how I'd feel about this show if I watched it now as opposed in 2010. But I have a lot of great memories of discussing this show episode to episode with friends who were into it, remember all the goodbye scenes, funny moments and that unforgettable ending. There's enough nostalgia and appreciation here to give it a 8 at least. I hope it gets enough votes to qualify, because the poll does need more genre diversity.
Random note: This show actually inspired me to pick up piano so I could play this song
Nominating Outlaw Star...which is basically just an excuse for me to spam Akino Arai music, Golden Time and Tora Dora.
