About the ending:
! The ending is not tragic. Though the movie supposedly has a different ending than the book, I'm pretty sure it's supposed to capture the spirit of the book's ending, which is bittersweet. The book ends years into the future where both men seem happy in their heterosexual relationships.
If they are going to be less dramatic about it and change the ending…
! i see both of them running to each others arms after some realization: and let an open ending i dont like the idea. Hope they do better :s
