i give this movie a chance only because it have very good review . after see the trailer i think what an unfunny movie full of clichés . but i decide to give it a shot because trailer often do not portray the movie very well . what a waste of time . the movie be worst than the trailer and after spend 2 hour watch it and i couldn not recall one single line that make me laugh . the funny part of the movie be the csi parody and but that also be pretty passé . i couldn not relate to any of the character nor hope that they will be together and because i find them utterly stupid . the plot be extremely predictable and inconclusive . unintelligent comedy for people who be either still in high school or feel that way mentally .
