My family of four was blown away. You'll love it even if you're not a Star Trek fan, although you do need to appreciate good science fiction or space opera. My best advice: stop reading reviews. I read a spoiler that I didn't realize WAS a spoiler until I saw the film. Just go see the movie!
I liked the movie, but I felt a bit confused after seeing it—after all, they had to edit the story down to two hours. I just had trouble understanding what the audience would have understood if they didn’t already know the story--I had read it four times. I heavily questioned my daughter and mother-in-law, since they hadn’t read the book. I think the thing the movie left out that it shouldn’t have is a very clear explanation as to why Edward becomes as obsessed with Bella as she with him. Other than that, it was great! I thought that the cast was very good and my very favorite sequence was the baseball game. (Though maybe that’s because it’s my favorite song from the soundtrack?)
