Saturday Night Fever
Spoilers for anyone who hasn't seen in the movie:
I don't think Stephanie should've forgiven Tony for what he did.
Yes he realizes how terrible he was for nearly raping her as well as how bad of an influence his friends were on him. But, still, just because you realize what you do is wrong and apologize doesn't mean people have to forgive you. And I think attempted rape is a pretty unforgivable action!
It almost felt like they had a sadder ending but the test audience didn't like it or they rewrote it before it was ever filmed because they thought audiences wouldn't like it. Still I think the movie should've ended with Stephanie not letting Tony into her house and then he walks away, rejected, wondering what he's going to do with his life next. I mean it literally begins with him walking why not end it with that as well?
