My personal favorite for flawed reasons is Madoka because I was there for the live reactions to the infamous episode and it was magical watching everyone lose their shit. It was also my re-introduction to anime after being shamed out of it for liking sailor moon as a kid.
Sorry, but I can't think of anything to recommend right now. Honestly I've been a bit bogged down with assignments to watch much recently.
Good luck with those assignments! I doubt I can be any help, but post here and I’m sure a lot of us are gonna try to be helpful. Wreck that school shit comrade!
