Okay, I warmly recommend JCVD. I thought I knew what to expect, from the trailer, but I had nfi... and I mean that in a totally positive way! Don't read the spoilers and you'll find the plot to be pretty surprising.
The script is good--original, cool, funny!--as is the direction... and van Damme is much more of an actor in this movie than he's ever been before.
Apart from an annoying monologue somewhere near the end, I enjoyed every minute of JCVD. I actually feel like watching it again!
Give it a look if you get the chance. I think many--if not most--of you will find it totally worth your time
