This film is crap! 4 teenagers run around a school for an hour and a half screaming at each other "why me, why us". no time travel, no killers, no explanation! just a cheep rip off of the 13th floor and the matrix, really that's all you get. not even a decent ending. the only reason this got made was she's martin scorsese's daughter. 0 stars and not even a good sized asteroid!
