Accell World was incredibly boring.
Long reviews waste your time, so here's one paragraph.
AW had me going for the first couple of episodes and I even wasn't bothered by this pathetic cheeseburger of an MC. The animation rocked and the music was fine. Somewhere along the line though, the story just didn't accelerate(heh...) and the MC NEVER GREW. This dude is a pussy from first to last. Because of this, you can never root for the guy or feel sorry for him when bullshit happens. All in all, AW is a boring waste of time centered around a cheeseburger.
-Variety of characters.
