I don't know if I even want to see a trailer for this one, let alone 20 minutes of it. Just give it to me full on.
I basically feel the same way, seems like a waste of time just to see how things are shaping up for a film that is only a few months away from release, even if it is free and in IMAX 3-D. I've mostly even given up on playing game demos until a week or so before release. It just seems like a bit waste of time when waiting is hardly that difficult. Besides, then I'll find myself, after twenty minutes, potentially saying, "That's it? I have to wait even longer to see how everything ends?" Then I'll be pissed off, caught up in hype, and impatient. Of course there's always the chance that I do not like the stuff either, but for a film like Avatar, something I will likely see regardless simply because of the spectacle, I do not want to take the expectation that I will hate it into the film either.
