How the hell did this mediocre film get such a high rating?!

Rating: 3/10 (17 October 2009)

I don't understand what's so special or unique about this film?! Is it because people believe it's based on real life events (which in actuality it's not. (see trivia section)), or is it because people in small-town America relate to it? I didn't come across any amazing prize winning performances by any of the characters. The plot is basic, the outcome when things start getting out of hand where the criminals make one mistake which leads to another is inevitable, the sheriff's work isn't amazing!, there were no shocking twists - all in all, a very simple film - I'm at pains to identify why people have rated it so highly.
In summation, I didn't hate the film, or dislike it that badly, it's an OK film - but it's nothing special. I'd give it a 3-4/10. Don't come in expecting something amazing - as I did - else you'll set yourself up for a disappointment. It's very mediocre - but watchable - if a bit mundane. And what was going on with that old school friend of hers? Why did they write that in!?!
