Let's be honest: This (S2) season is kinda like a "short representation" of the manga with some cool moments and if you view it like that and re-live the manga in an animated(even tho not the greatest one) manner, you'll be able to enjoy it alot.
If you stick with the good memories of S1 and you can't get over it - well, then you'll probably drop it.
For me - I enjoy watching it, no matter the factors I just described.
Peace.
