Everything has already been said about this film in the adjoining comments, so I'll make a few personal observations.
I'm not about to apologize for liking this film, or make any excuses for its content. Frankly, who's to say such a town can't exist? My origins are in the Deep South, and believe it or not, I've seen communities like this one. Perhaps it is "stereotypical" to think that such a town CANNOT be real. Sure, hatred exists everywhere. I've personally been the victim of a nasty hate crime, but I've also been fortunate enough to visit small communities that embrace everyone, gay or straight. I have every reason to be bitter, but I choose not to be a martyr.
As others have said, I welcome this film as a gay love story that avoids the pitfalls of torpid melodrama and morbid angst. Many have accurately compared this film to the TV series "Northern Exposure." It really is a sweet little film (and I normally avoid that word).
How interesting that ALL of my cynical gay friends love this film. Surprisingly, I only learned of it this year. Ebert totally missed the boat on this one.
