"Sabotage" finds Arnold Schwarzenegger briefly pushing his persona in a new direction. It's not simply that the film is unexpectedly more murder mystery than action thriller; "Sabotage" is easily the meanest, most vulgar and most violent movie on Arnold's resume. Credit where credit is due for trying something new, but considering the film's brainlessly scummy ugliness, it qualifies merely as a not-quite-noble failure.
