Prince of Persia: I liked this well enough. It seemed really popular to dump on it 6 months ago, but maybe it's been long enough that people can just enjoy it now. It doesn't follow the plot of the game(s) very closely, but as a big fan of the games, I was still pretty happy with it. I don't think the game plot would adapt very well to a full length feature. Not that there's anything wrong with it- it's a very good setup for a game.
I found the backhanded compliment "It's pretty good! For being based on a video game, that is. <knowing smirk>." And, "Well, it's the best video game based movie ever, but that's not saying much. </superiority>" I thought it was decent enough, videogame adaptation or no. My wife enjoyed it two for what it's worth.
BD from RedBox for $1.50. Might pick up the BD for $10-$15 in a couple months.
