this attempt to mix two genre of american pie type and alien type do not mix well . and it seem this be due to lack of try rather than difficulty of mix . such waste of time both for maker and viewer of the movie . the movie try to follow clichés of both genre but the result be not convince like the guy who stipends relieving of his virginity and and more unbelievable that be the caring and responsible alien type who think for a specie that their survival be base on their distinction . another unbelievable thing be the police that in camp with so much strange happening do not suspect anything . these type of movie success be base on viewer suspension of disbelief . but unfortunately here this disbelief can not be suspend . and this be because of lack of try on writer and director side .
