To be honest, I didn't expect much of this film, given that it was being shown at 1 o'clock in the morning when no one would be watching, and the trashy title but it's a good little film.
Michael Madsen is good as the main character, who you root for despite his unsavoury nature. The supporting cast are also good, especially his ex-wife and her new husband and Agent Gottfried.
The tension ratchets up well, and the film moves along in a logical progression. Also, unlike many thrillers, there is enough revealed for the audience to work out who the Sweetwater killer is, without it being obvious. There are no illogical twists and turns which is always nice to see. The scenes with the killer are suitably scary, especially when the killer attacks his third on-screen victim.
The ending is good and well done, as is the rest of the film. It's not a classic, obviously, but watching the film is not a bad way of spending a couple of hours.
