i completely disagree with the previous reviewer represent this movie have amusing moment but hardly a laugh riot . ( unless you really think sip from a septic tank and head explode in a vice be a laugh riot ) in fact and the only reason i give this a 2 instead of a 1 be because a . ) two of the actor be decent b . ) the soundtrack be above average with some tuneful pop song throw in for contrast and c. ) the monster truck be pretty terrify . other than that and this be a movie with some intermittent and creepy or interesting idea which be overwhelm by unrelenting crassness and crudity and vileness . the former best friend character be one of the most annoying i have ever see and the small grace that the hitchhiker character have disappears in yet another contrive twist end that make little to no sense at all . a waste of the lead actor who show some nervous charm and the aforementioned actress portray the hitchhiking character .
