S1 was outstanding! And the first 3 episodes of S2 are great, but after episode 4 wtf happened. I didn't even read the manga, yet I'm still disappointed. For me the series was too rush and it could have been better. The last time I was this disappointed was S8 of GoT. I guess I'm gonna read the manga to fill the void the series left me with, because it looks like the series won't have another season.
