Does anyone remember the name of this movie, It was shown to me a looooonggg time ago, I think it was like with this girl that had really long nails, and she used to be bad, but then turned good. It's a very unrealistic movie, they all had some sort of power or something, and I remember that one of the bad people was a Gothic looking girl that could kill people by kissing them & taking their oxygen away. I also remember there were flashbacks in the movie of a little girl being in a white room and her parents were killed by a monster or something. I can't really remember anything else and I'm not sure if it was a horror movie or not but it seemed like it to me at the time.
Please help, would be much appreciated ~
