Idiotic ending ruined the movie (Spoilers)
A potentially great movie ruined by a ridiculous, illogical, contrived ending.
In the first place, how did Kristen know that it was Will who shot Jim? There was a whole jail full of people who wanted them both dead.
If she did happen to see Will, why didn't she just have him arrested for murder? And if she did want to kill him (per her conversation earlier in the movie with Jim), wouldn't there have been an easier and less dangerous way than by hiding in his car?
Why didn't Will (or whoever the killer was) finish the job and kill her? Especially if she saw him, wouldn't he have made sure to kill the witness?
Why were she and Jim staying in the trailer park, with the windows open, and no police protection?
Why would homeless people hangout in Will's car? Do homeless people make it a habit of finding shelter in the car of the town's biggest badass?
If Will thought it was a homeless person in his car, wouldn't his reaction have been more shock than amusement when he saw it was Kristen?
Why was she free in the first place? Perjury is a felony, and a cop who commits perjury (which she did) would get the book thrown at her.
Stupid, stupid, stupid, stupid........
And one more thing - Greg Allman is a fantastic musician but he can't act worth a damn.
