JCVD is the only reason you should watch this..
His scenes were actually funny. Rest of the movie had FEW funny moments but overall I was bored to death and only waiting for Van Damme to come back into the story (was kinda obvious that they wouldn't just kill him so early).
So yeah, watch it for JCVD, it's worth it (thought I guess you can just watch some YouTube compilation of his scenes from the movie).
