I love video mash-ups.
Speaking of 300, over at Kung Fu Monkey, screenwriter John Rogers has an interesting perspective on the arguably "anti-American" sentiments that keep popping up in the movie--the relevant post is subtitled "Why does King Leonidas hate Private Ryan?" Provocative stuff.
Personally, I'm happy to accept 300 as the lighthearted romp that it is. Sure, it wants to be all macho and loaded with gravitas and artfully-story-within-a-story, but there just isn't that much there. It gets the job done, but apart from the visual effects--which are absolutely stunning--doesn't break any new ground in the narrative department. Nothing wrong with that, but don't make it out to be more than it is.
I'm hoping the director, Zack Snyder, digs a little deeper with his next project: the also-often-declared-unfilmable Watchmen. Drool.
