Not sure why there's a lot of hate thrown at this show, but I am only in the first season, so take that info as you will!! I'm quite picky about anime and have enjoyed series like My Hero Academia, Jujutsu Kaisen, and Demon Slayer. I came across Blue Exorcist on Netflix earlier this week and thought the animation style was great, and the story and characters were entertaining and funny. Not a whole lot of development yet, but, again, just in the first season. My only real complaint is the lack of direction. I'm not sure where this series is going, but I'll keep watching and see what happens!
