I love this movie, am deeply moved each time I see it. You can see the plot from other reviews, so I won't review it here. I've often wondered whatever happened to Lukas Haas' career - he was outstanding. This movie is a refreshing change for Harrison Ford, who previously was known only for Star Wars and Indiana Jones. He shows new depths and range in his acting abilities.
My main gripe is that mentioned by others - the "out of character" scene where Kelly McGillis lets Ford gaze at her while bathing. No Amish woman would ever do that. That was simply a cheap way to sneak in some modern nudity, into a culture where it would not be tolerated. Other than that, it's a nearly perfect movie, suspenseful, funny, romantic and interesting.
Has anyone noticed that Viggo Mortensen is in this? Look for him in the barn-raising scene. Little did I dream when I first saw this movie almost 20 years ago that while I was watching my heartthrob of the time (Ford) I was also watching my daughter's present heartthrob (Mortensen aka ARAGORN). Fun glimpse of his early career.
