Having read the book, everything about this movie was wrong, in my opinion. The characters in the book read as self-indulgent, out-of-touch post-Ivy Leaguers, but at least you have the benefit of being able to read some of their back stories. You know NOTHING about any of them in the movie - the viewer is given no reason to even try to care.
I said to the person with whom I watched this, the most interesting thing about this movie is the music. And the music wasn't even that interesting, nor was it present as much as it could have been. I felt the movie was wholly miscast. Anna Paquin, while blond, was nothing like how I envisioned Lila while reading the book if only because she was about a foot too short. They took the one interesting feature of Laura's away (she's Jewish) and removed the part that really set her apart from her WASPy Yale buddies. Elijah Wood, while talented, was not creepy enough to play Chip, the bride's brother and Candice Bergen was not severe enough to be Augusta. I was also disappointed that they diminished her part - she kept everyone on their toes.
I highly recommend skipping it all together. I wish I had that hour and a half of my life back.
