Given the amount of fanfiction written of the variety where Ennis gets to find someone, and live "happily ever after" in a melancholy way, kind of a bittersweet trance of a life Jack created for Ennis by Jack's "sacrificial" death, it's no wonder to me that so many people feel put off by the story after they fall in love with the film. From an optimistic perspective, the story sucks. It's a ringing, bitter condemnation of either or both of (a) society's homophobia; and/or (b) Ennis's own lack of strength. At the same time, it's a pretty amazing depiction of a deep, but flawed, love between two people, and a short, sharp, insightful analysis of human character. The point is, Ennis is screwed at the end of the story, emotionally, and I don't see any redemption coming his way.
The film, of course, gives us the hope that his experience with Jack will open him up to other loves in his life (e.g., attending Jr.'s wedding). I see my own prejudices, founded in the story, making my way into the interpretation of the end of the film. I certainly DON'T believe Film Ennis EVER finds another man, let alone a Jack replacement! I think he only gets bittersweet solace from the resolve not to let work get in the way of his loves anymore.
Sorry, now I'm the one going on about the film. Point is, the story is arguably unrelentingly bleak; the film gives some light to Ennis's tragedy.
BTW, I'm on my non-Mac machine here at work and I can't fiqure out how to spell check this thing! If someone could let me know how. .
