It wasn't horrible, but an average rating of 8 is excessively generous.

Rating: Null/10 (19 September 2010)

I would give it between 5/6 out of 10. The movie was very watchable, kept my interest, had a cool filming style, but I just felt meh about it. First: the acting. Now I remember as a kid going to see JGL in 'Angels in the Outfield,' so he's an actor that while I'm no huge fan, I'll watch his movies. He's charming in the role of a love-sick, naive young guy. I especially got a kick out of the dancing scene. A totally random scene, but it reminded me of how occasionally when we are extra happy, we start dancing. In our rooms, in the copy room at work..sometimes we just get happy. As for Zooey D, I don't see her appeal. I don't seek out her movies, but every movie I've seen her in, she's a quirky, flakey, Mary Sue. Is it always the role or is some of it her real self poking through? I don't know. However, it reminds me of Drew Barrymore....she just has a ditzy quality that gets tiresome when it's in every movie I see that she happens to be in. I also didn't find her to be the best-looking lady in the movie, so all of the intro in the beginning about her was a bit hollow. I thought the redhead blind date was much more attractive even if she had 5 mins of screen time. This plays into the Mary Sue aspect of Summer's character.
As for the story, it was clear that the movie would end up being about how he got over Summer. OK fine, I was looking forward to that. However, the execution left a little to be desired. Tom definitely allowed himself to be used by Summer, however, I'm of the opinion that had she gone beyond her initial "I don't want a relationship," and nipped everything completely in the bud, he would have gotten the hint. Summer had zero redeemable qualities in my eyes. She definitely used his feelings to her benefit, and if the roles were reversed, Tom would be the quintessential jerk. She was highly manipulative and she just strung him along. Something was definitely wrong with her in that she was OK using him KNOWING his feelings w/her. It was easier to identify with Tom and all his ridiculous naivety bc he was emotional. We knew his motivations, but did not know hers. When I watch movies, whether I like characters or not, I feel writers should give us inclinations as to their motivation. Note: this doesn't make them likable, it just makes them more understandable. There's absolutely no reason to act "relationship-y" with a person whom you KNOW wants it when you don't. After a fight where the guy/girl is upset bc he feels that you're in a relationship but you won't admit that it kinda is....only a girlfriend/boyfriend figure goes over to that person's house in the middle of the night and sleeps with them. Not a person who wishes to have boundaries. None of her behavior said "friends."
The part of the movie that killed it for me was when she got married and told Tom that with the new hubby "she was sure of what she wasn't sure of w/Tom." *Cue head scratching* So was that a throwaway "insightful" line or was she lying when she said she didn't want a relationship? She got married very soon after she met Tom, so w/that scene, the writers negated a lot of personality and just made her a completely unlikeable character.
The ending was a bit cheesy, but whatever. It's a decent movie to pass time, but you'll probably leave with the same "meh" feeling I did.
