You've quit right after the last filler episode. After this one the series gets really amazing.I gave up on the original E7 series around the 43rd episode or something like that.. when they were playing soccer or something. Is the end any good?
The hate for the pace is quite understandable. The 3X episodes are really horribly slow and contain too many filler episodes (including the worst filler episode ever, that football episode was a disgrace). Once it gets going it gets spectacular though.
