Gotta agree with the others. Starts off great but really falls off the deep end. That ending too...
Spoiler: show
By starts off great you mean the first 2 episodes are awesome then we get bait and switched with awful characters and a terribly boring plot. It's like Guilty Crown or Cross Ange, but nothing funny happens.
The best part about Rolling Girls, by far, is the music. Pretty much all of the music are covers of songs by the Blue Hearts.
