This film made me angry

this was my first time seeing it in its entirety. I was nominally aware of the general history of it, being adapted from Bizet, and I knew who starred in it, but I hadn't seen the "original", either, so I was coming into this relatively cold.

the performances, the music, the cinematography, costumes, etc., were all top-notch. I wonder what all awards the film won-

But the narrative, especially toward the end, kind of made me angry. It just didn't seem to make sense. Early on, Carmen manipulates Joe. She convinces him to not take her to jail. She deliberately seduces him even after finding out he's got a girlfriend/fiancee. Despite declaring his career ambitions with pilot school, she convinces him to go AWOL and go to Chicago with her on a whim-- but while there, they're both basically broke, and Joe's career prospects get dimmer every day he's AWOL. Then all of a sudden, her attitude becomes that HE's cramping HER style, getting in HER way, holding HER back from "freedom". It's a total 180 without any particular justification. Despite the flimsy nod to being superstitious, ultimately Carmen comes across as recklessly selfish. And Joe, despite being relatively even-headed for most of the film (despite his unfaithfulness), all of a sudden diverts into obsessiveness and murderous impulse (Even the abrupt ending didn't make much sense-- nobody in Husky's camp noticed Carmen being swept away? The janitor who discovers Joe strangling Carmen doesn't intervene himself, but decides to go get some military MP's? Even the strangling itself seemed to last barely 5 seconds before Carmen is presumed to expire.)

Since this was clearly meant to be a tragedy, it seems like more could have been done to flesh out Carmen's character; as it stands she is more or less portrayed as just a good-time girl who scarcely cares about herself let alone anyone else around her.
