It is hard to believe that a someone of Michael Douglas' stature would be part of this trash. The paper thin plot attempts to justify the outrageous antics of the loser main character. If there was any kind of chemistry between the characters or a creative plot connecting the ridiculous sexual scenes, I would have a different opinion (I like Michael Douglas). But, this movie is just a series of empty, shock value narratives with meaningless, non-stop cursing. The last scene is an attempt to make one think about what the main character would do next. But, by this time, you really don't care.
If Michael Douglas thinks he has to do a movie like this to sustain his acting career, he must be as desperate as the character he portrays.
This movie is a vile mess.
