Lets say this straight off the bat. Season 1 will make you want to rip your hair out, kill many characters and stop watching. The story itself is quite good. But its the characters you wanna get rid of. Many of them feel like they were made to have 50 IQ. Art and sound wasn't bad at all. If you do manage to watch the entire thing, you'll be in for a treat.
Season 2:
This really suprised me, it was thousands of times better than season 1. I wont spoil but there were some problems worth mentioning. One, there really are some plot holes and 0 IQ moments. The story gets way to confusing at moments especially in later arc's. But overall its still a 8.5/10. It improves on everything S1 did good and fixes everything it did bad.
Spin off's/OVA's:
Nothing special here to be honest, they aren't bad aren't great.
That being said I do think the alternate universe movies are worth a watch. I really enjoyed them.
Anyways I doubt many people will ever see this review. Still I hope this'll help you.
