The first 3 seasons- and movie- was absolutely phenomenal. It consisted of developing characters with marvelous action-packed scenes to punctuate the storyline. But season 4 so far- ep. 9- is proving to be a convulsion of emotions, as they are beginning to explore amateurish characters too indepthly in my opinion, making the anime move at a boringly slow pace.
And the fights are becoming too sluggish, following the format of the good guy initially being overpowered, then suddenly, a flashback into his/her future and now, he/she is suddenly overcome with power. Perhaps I am judging to harshly but I really had high hopes for season 4 but so far it is incredibly hard to watch
