I didn't read the manga much, but I watched all the episodes. I really liked the Soul Society arc, Ichigo's fights against the Shinigami were cool. After that came the Bounto arc, which was filler and made me puke, several times. What's worse is that three of those horrid characters from the filler arc remained in the anime to screw up even some manga episodes. Arggh.
Anyway, after that the whole arc with the Espada coming was very cool as well. However, regarding the manga, I feel Bleach is slowly coming to a conclusion. Mr. A is, you know, the fire thingy, hm hmm, and the Espada are slowly being dealt with.... It's only a matter of time until Mr. A releases his hm-hm-kai and the final battle engages.
Hope it was subtle enough for those who don't wanna be spoiled.
