Sure, Batman and Catwoman are super attracted to each other. They also have similar lifestyles. The problem is that one is a crime fighter and the other is a criminal. He's all like, "I will never kill anyone," and she's like "I kill or try to kill people constantly."
This relationship only existed in a fake universe. I think. The only way for them to be together was for the world to end, or something. I don't know, this was a confusing movie. I just know that these two really weren't meant for each other. If your relationship requires armageddon to work out, for God's sake, move on.
This couple is either lying to each other, or lying to the police, or trying to murder on or the other. It's super messed up. I don't want to spoil the movie, but they'd both be better off just moving on.
He was sent back in time to protect her from a killer robot. They ended up hooking up, but only because her future son spent his life convincing Kyle that Sarah was super hot and that she totally bang her. Gross.
If the only way a couple can work is by slaughtering people, then maybe they just shouldn't date and should get professional help instead. Also, if they do get arrested and imprisoned, don't put them in the same prison. Just in case.
She dumped him because it turned out he was a professional thief, and she wasn't aware. He also spent a bunch of time in prison. Then he robbed a casino to prove his love for her, which she ended up being okay with? Yeah, that's not how relationships are supposed to work.
The main characters of the first Scream movie had some real problems. First, her mom slept with his dad. Then Billy murdered Sidney's mom, because he was mad. Then he killed a bunch of her friends and tried to kill her. It's probably best it didn't work out, because that's not the basis for a healthy relationship.
Bella Swan and Edward Cullen met when he saw her and thought, "I want to drag her into the woods and drink her blood!" and she thought "Hey, he's cute." He's also something like a century older than she is. It doesn't get creepier than this.
