Animated is okay, but fillers annoy me and I don't really like sitting down and watching TV very often... If you read the manga you realize that certain filler arcs could have been done without and you wonder why they were done at all, and it's just generally frustrating. The manga you can plow through without fillers and everything makes sense...and you don't have and extra chicken, turtle, and rabbit running around for no real reason. And fights don't get cut off in the middle and continued after the application of Mr. H's parallel universe theory gets for a whole pointless arc that gets shoved in the middle of said fight before they refocus and go back to the actual plot and which no one remembers a thing about later... For instance I've been told that after his arc, Shusuke Amagai never gets mentioned again.
