Yes, it is true, I did go see Twilight opening night. Not the 12:00 am showing, just the 7:50 pm. There were plenty of swooning teens (and non-teens) who cheered and/or screamed when Edward first appeared on screen, as well as at other key moments, but overall, I think I only missed one line due to excessive cheering. Not too bad, I must say.
And as you may expect, I have opinions. (Who, me? Shocking, I know.) Overall, I liked the movie, if only for the fact that I loved the book. Is it as good as the book? No. But how could it be? To condense a--what was it, 600-some odd?--page book into 2 hours is quite the feat I'm sure. To cast actors who portray the characters as seen in the heads of millions of different fans is virtually impossible. But they did their best.
I thought it was a little cheesy (as expected,) very funny, (unexpectedly) and well cast. I loved Bella, and Edward grew on me. I think I would have like him better if they had spent more time on the first half of the story. It felt too abrupt and skipped too many scenes (like the blood-typing!) to fully develop Edward's character and the tension between him and Bella (or is it he and Bella?). I think it would have been much better as a three hour movie. But maybe that's just me.
I would love to hear from someone who had NOT read the book, but did see the movie. I'm of the opinion that it would have been hard to follow and ridiculously cheesy for someone without more Twilight background, but I could be wrong.
