I've got a lot of time for Dwayne "The Rock" Johnson, I think he's extremely charismatic and can actually act!
I'm not sure how far he could be stretched on the acting front, but with the stuff he's done so far (I *still* need to see Be Cool and Southland Tales), he's been pretty good. He's a solid action hero, that has absolutely no problem with a helping of self deprecation, all of which makes for an entertaining watch. Give him a good script and a good director and see what happens.
As for Walking Tall, based on a 1973 film and real events, we have Chris Vaughn returning home after 8 year's army service, to find his home town ain't what it used to be. He gets pissed off, beat up and sets out to put things straight.
This is another film that I've been waiting ages to see, and well, it wasn't as good as I was hoping for. It's a tad slow and choppy, Johnny Knoxville was pretty lame, and the script wasn't the best, thank the lord The Rock was in it tho, that made it watchable.
