Bill Murray was great in this one. I think he's better in this sort of film than in comedies. Perhaps it is because he is very believeable as a somber depressed guy.
The film is pretty slow paced, dependent upon body language to convey quite a bit. The neighbor Winston (Jeffrey Wright) is hilarious (you may remember him as Peoples in Shaft). He really makes the beginning of the film.
The film is worth watching simply for Alexis Dziena's nude scene. WOW!
The ending was somewhat...blah. But appropriate.
