So while we're waiting for The Avengers, anyone planning to see this? (Trailer is here.)

I have to admit, my first reaction on hearing about this film was that it was the stupidest movie premise I could think of. But having seen the trailer . . . it actually looks kinda fun. I'm expecting zero story, but a big shoot-out between aliens and the US Navy does sound like it'd be cool to watch. Anyone gotten an early look at it?
