I recently saw this movie with my friends and found that the movie is not worth to give 3 stars also. Ya at point it is good, somewhat funny also in some scenes, but overall you will feel bored and above from all, the story is very predictable in the first 15mins only.
Renee was so wasted in this movie, I mean anyone can play this kind role, and there was not at all something special. However Harry showed some decent performance. The rest of the cast, including Siobhan Fallon and Frances Conroy, is very nice, too.
As for the setting in Minnesota (actually, the film was shot in Winnipeg), it is harshly beautiful while the costumes are a mixed bag, with Zellweger looking Great. But, that means little, if the script and direction would have been little polished, then the movie would be even more funny and full of life.
I would rate just 2stars, an Ok to watch (If you really want to).
