The cast were fine but I saw nothing comedic in this movie whatsoever.
Other reviewers thought it hilarious.
I'm afraid I just found Harrelson's character sad, that's how he remained throughout the movie.
Sad and somewhat pathetic.
I love Woody Harrelson. He delivered himself as he does so well, an ironic character, well meaning but selfishly damaging those around him.
Funny? Hardly.
