This movie is simply implausible and convoluted.

What hits you early on is that it seems like a SAW wannabe with all the elaborate and gory executions. It's hard to believe someone is so prolific at building complex execution staging without leaving a trail of evidence. They should simply be caught when the law traces where unusual quantities and specialized items have been purchased.

The FBI seems lethargic and terribly ineffectual from start to finish. I find it hard to believe that NSA could not be tapped, in confidence, to help put and end to something so heinous on the Internet.

Other goofy stuff includes hiding one FBI agent in a seedy motel for security, an insanely fast web hit counter, and an FBI agent dumb enough to climb back into a car that's obviously rigged.

The only entertaining scene was seeing the psychopath get it good in the end. Other than that it is mostly "Why the F*** did they do that?!"
