That's what you get for being 12 hours ahead of us. I've been tempted, but it all depends upon the Czarina. Back when we were both married to other people, her now-ex-husband was the person who turned me on to The Blair Witch Project, and I managed to snag enough preview passes for the critics' screening in Dallas so the two of them and my now-ex-wife could watch it with me. The Czarina shares with my mother the ability to get violently seasick when watching documentaries on yachting, and she almost needed to be carried out of the theater after the preview. If Cloverfield is as bad with the Sam-O-Cam camera jiggles, there's no way she'd be able to watch it on a big screen.
See once I'd seen the clever video trick and thought, "Yep, clever," I was then waiting for something else. I suppose I expected the plot to be equally new and interesting. Silly me.
Even though the monster was very well done, I remained unmoved. Unless that was b/c it had turned me to stone, in which case, Woo hoo!
And to add something of actual value to this thread - one of the reasons I really liked it was that I felt much more involved in the film, since usually I'm just an observer of some people on screen doing stuff.
It had the feel of a good Cthulu-esque roleplaying session :)
