There are several holes in the story of this movie... if you're one of those people who gets hung up on that, move along. If you're able to immerse yourself into something and just enjoy it, then I would recommend this movie... quite enjoyable.
I'm not a fan of it being billed as a "gay" movie; when Lee Todd enters the world of Griffith and Emily, and their slightly crazed Aunt Selma, Griffith for the first time has someone that he can consider a friend (besides his beautifully controlling cousin Emily, who desires more than mere companionship and will try anything she can to keep him in their native small Mississippi town).
I don't think the words "gay", "queer", or "homosexual" ever enter this movie; while the characters develop a love that is self-admittedly stronger than friendship, that's really what this movie is about. Griffith's frustrating love and sense of responsibility for his crazed aunt, Emily's obsessive blinding love for Griffith, and Lee's protective love of Griffith...
Add in an interesting subplot of a dark family secret (that had so much more potential that it actually delivered) and it's an interesting concept.
Having grown up myself in a very small rural town where few people ever leave, I related to the movie and thought that even if the story was a bit weak, it was still beautifully delivered.
