The Punisher kills a whole lot of bad guys in fairly entertaining ways, so not too much to complain about. Plot is decent but hokey (and down right cliche in some scenes), but still worth the price of admission.
It's certainly a mediocre comedy worthy of a rent went you're bored. Their seems to be, at first, chemistry between Vince Vaughn and Reese Witherspoon, but by the end of the movie you'll barely believe they could be a couple. The ending is rushed and equally unbelievable.
