I THINK that I pretty much know the plot of the movie (feel free to tell me I'm all wet, of course... but I'm fairly well convinced). So I'm largely "spoiled" already. If I show up and the movie that I see in the theater is totally unrelated to what I read before, I'd be shocked... though it might be more fun that way.
Side note... I knew that JJ Abrams and I were "nearly" the same age. I never knew 'til today that we were born on the exact same date, and within about twenty minutes of each other! And worse yet, his glasses are in the same frame as mine. Same height, same hair...
Spooky stuff... I'm getting that whole "separated at birth" vibe right now!
The main difference is that the guy is a heck of a lot richer than I am (though, with my new job I'm starting in a few weeks, I'm now officially WELL into the six figures, so I'm catching up!)
