Do yourself a favour and skip the filler, it's why so many people dislike Bleach
(You could always come back and watch the decent Zanpakutou Rebelion and Mod Soul filler arcs later on, just don't watch them before finishing because they're placed in the middle of the important arcs and have no connection with them at all).
I actually want to watch the filler. Part of the reason for me not enjoying Bleach and Naruto anymore was the lack of character development. The filler might solve that.
