10 Romantic Film Relationships That Definitely Wouldn't Last

6. Danny And Sandy - Grease

Because what relationship isn't going to succeed when both people are constantly trying to change themselves for each other? Don't be fooled by the magical car flying off into the sunset -- Sandy and Danny have some serious problems. But you can't judge them too harshly. After all, who hasn't met someone on vacation that was a totally different person when you see them in the real world? The difference is, most people would chalk that up to a summer fling and move on from it, not try and force a relationship that clearly isn't meant to be. First of all, Danny is a total jerk to her. Come on, if you're lucky enough to get with Olivia Newton-John, you do not throw shade at her in front of your friends to try and look cool. He's torn between wanting to act like a genuine human being, which Sandy likes, and acting the way a teenage boy thinks will get him laid. And Sandy, well... the girl is just a mess. You are a bright, beautiful, wonderful (if ridiculously naive) person, don't bust out the black leather just for someone who wasn't treating you right in the first place. In summation, Sandy and Danny are just a train wreck, but will probably stick together and pop out a couple of kids before they realise it.
