This.

It almost never gets better later, in anime. It goes the other way around.

When live-action TV shows get better in second seasons, it's often because the acting cast find their groove and learn how to play their character, and the writers learn how to produce scripts that work for them.

Anime largely doesn't have this.

In anime it often starts strong because you have the excitement of new characters to meet, a cool new world to learn about, a great premise, some looming mystery. But once all that's done with it fizzles out.

Sometimes it doesn't even last a season before it takes a dive. And it's because all the writer really had was a grab bag of cool ideas, and not really a story. And once that initial excitement is over there's nothing left.

Promis.....

Yeah, I really didn't like No Game No Life's second season, damn

there is no second season of Psycho-Pass :)

Durarara.... Granted x2 isn't THAT bad it's just disappointing.
