I actually really like Bleach, but I can't pick out what it is that attracts my attention. I just like it. Oh, and do you really really hate fillers? Thats what bothers me the most.
I gave Bleach what I consider a fair chance. I have read all of the manga and watch the anime up until they went into Heuco Mundo (wherever Aizen is based). I check in every now and again because I think it has so much potential, I hope it actually cashes in at some point.
Yes, I despise fillers. Both the filler arcs, and the added flashbacks, etc.
Exceptions - Land of Tea arc was done acceptably, and it was placed well. Had it been in the middle of the long batch of fillers, it would have scored worse.
I also really like the first Naruto movie. I know it is not a filler, but of the movies to date, it is the only one that I would consider watching again.
