Watched a midnite showing of Sucker Punch last night....
Emily Browning is mesmerizing to watch, and the fight choreo/action/effects was awesome as all get out.
But damn did the story leave a little to be desired for me. Luckily pretty girls with guns is enough to get me through the movie! To me it seemed like Zack Snyder's love letter to all that he loves about action movies...a long-form music video if you will.
I will say that the soundtrack to this movie is pretty well done, and I will seek it out to add on my iPod.
And what was up with that weird music video during the end credits.

It's beautiful to watch on the big screen for the complete surround sound experience, but other than that, I'd say wait for the rental.
