the interesting part is when you are binge watching you don't even need to refer a filler list to identify when the filler starts be it naruto, fairytail or bleach, fillers immediate mark a steep degrade in quality.
I agree aizen's death and loss of shinagami power should have been a fitting end to the story. however as far as i am aware Tite Kubo had to finish the series in a hurry towards the end and there could have been a lot more. Of all the anime's i watched so far. 2 of my favourites bleach and fairytail both have not got the last manga arc in anime.
