I like Emma Thompson's films and chose this movie because of her. However, I was moved by the realism of this film to a degree that I did not expect. Watching Thompson and Hoffman was like seeing real people in moments of embarrassment and pain. If that doesn't sound like entertainment, it isn't, exactly. It is, however, enlightening, especially if you've ever been in a similar situation. The film also touched me because it exposed human frailties, such as Hoffman's character displays, with humor and understanding rather than with judgment. As the film progresses, we learn to like and understand the characters, and the "happy ending" seems genuine, not contrived.
This is clearly not a film for people who expect a great deal of action, and the humor is subtle. Instead, "Last Chance Harvey" is a movie for those who enjoy watching characters slowly unfold and come to life.
