First, Mike Tyson in a film is never a good idea. Second, the premise – that what these guys did is somehow all okay, normal and understandable – is revolting. Third, the comic timing of the actors is clunky,  and the comedy dialog writing ( “we’re so fuckin fucked!” ) leaves a lot to be desired. Four, they rely too much on Seth Rogan-type physical abuse shit and potty-humor for laughs. Five, the Zach G character is really just a disgusting human being, one of the most disgusting, loathsome human beings I have seen in films in a long time; that I am expected to like him and find him funny is deeply offensive to me.  Six, the Chinese gangster is the second most loathsome individual I’ve seen in films in a long time. Seven, both Zach G and the Chinese gangster are UGLY motherfuckers – it hurts to look at them. Eight, the Chinese gangster has the most irritating way of speaking of any character in the history of cinema. Nine, the “love” story between the dentist and Heather Graham is totally pathetic. Ten, the series of pictures in the ending credits is really depressing and sad and leaves you with little hope that the human race is destined for survival.
