The Atmosphere of this Anime is getting interrupted by the Comedy Scenes, for example Tanaka.
The first Season has too much Comedy.
The Second Season is Kinda unnecessary.
The Third Season is the best Season, in my Opinion. Every Episode brings the Plot forward. And there are nearly no comedy scenes, so the Atmosphere isn't interrupted.
When you take all of this together this Anime is a 7/10. (without comedy this would be much better).
Note:
I recommend you to get as less information as possible about a Movie or an Series. It makes it much more interesting.
