There are some very funny scenes indeed but Farly is Farly, yelling, getting angry, fighting and fussing. If you like that you will love this. My favorite scene is where he faces the Eagle at her nest. "Why didn't you tell me you only wanted the shell?" What a great one liner.
Perry is a little stiff as a character and is more of a straight man to Farly's funny man. My only problem with the movie is that there are too many places where it gets slow. Part of it is because you are in the wild and it was a slower time.
There are so many great one liners that seem to have too much time between them. The inuendos are a bit much especially at the beginning. The older Indians are just great. And the scenery, especially of the Tetons and the Snake River are outstanding.
If you want to have a fun night with mostly the guys this is okay for that. My wife did not like it. Anyone who knows and liked Farly for his antics and his in character concept, you will just think this is a hoot.
