I truly enjoyed this movie. It came and went in the theaters very quickly, much to my disappointment.
Tom Berenger and Barbara Hershey are excellent as a mismatched pair. They do a superior job convincing us of their relationship -- in my opinion as good as any Tracy/Hepburn team-up.
The premise is slightly unbelievable, but if you suspend your disbelief you will really enjoy a fine romance/western/fantasy/adventure.
The only knock I have is the excessive use of profanity for no reason.
