I just saw it recently and liked the movie a lot. My only issue was The Rock, I just felt second hand embarrassment throughout that whole movie.
I concur, it's not that Dwayne is a bad actor either (think Walking Tall), but it's as if they told him to act like a cowboy and that was a bad decision.
I loved this movie(maybe not the acting). You guys should check out the review me and 2 of my buddies did on it via our Podcast. It's over an hour long, and super spoiler heavy. http://brokenbrainshow.com/?p=117
