Note the whole 3D thing? Yeah, with the glasses and all. And not the cheap-ass red/green ones either, the slightly-less-cheap polarized ones.
The movie? I thought it was pretty damn cool. I like the story, and it was pretty well acted-- of course, they had some world-class actors, so I suppose that was to be expected, but for the on-screen actors were all 3D figures. Still noticeably not human, but pretty damn good: when you see Anthony Hopkins, you know it's Anthony Hopkins. The hand movements are still a little stilted, the way the skin reflects and translates the light, the eyes not having lenses... subtle cues. Still, really good. When you first see Angelina Jolie shimmer her way out of the water, it's just... wow.
The fight scenes are really cool. There are just a few too many 3D "trinkety" shots (anybody remember Dr. Tongue's 3D House of Stewardesses?), but overall, the 3D effect was a pretty good addition to the storytelling.
There's less blood than you'd think, but there are some pretty good quick gory bits. Grendel is rather disturbing. There is violence, but it's a violent story. And a sexy one as well.
I'd say it's a good one to see.
