See, this is where you're supposed to just lean back in your most comfortable chair and think 'popcorn'.
I, for one, am pretty much only going to see this movie for the speshul FXes. And it'll probably be on a rented DVD anyway. I'll admit - I laughed so hard at the rampant cheese of that first big trailer. Epic cheese was epic.
(Naturally, they've completely missed the point of the whole shebang, but that's another story for another place and another time.)
