While staying in Minnesota and searching for a house, Amanda and I had the pleasure of watching “300” on a large LCD TV, off of a HD-DVD. It was a feast for the eyes.
I’ve read the reviews on Rotten Tomatoes (just now, incidentally), and while the “experts” aren’t fans, the general RT population gave it a reasonable 85%.
Look, it’s not about the story. The story is loosely based on an historical account, and it’s an interesting story, but it’s really about the spectacle. That spectacle shines in HD. If you have an opportunity to watch it on HD-DVD or Blu-Ray, I highly recommend it, just for the visual feast. If you are offended by blood and gore, however, find something else to watch.
