5 couples that make me very unhappy

And not just because I'm a slasher at heart. These pairings simply don't make any sense to me on a fundamental level.

Neal&Sara in White Collar: He just lost the love of his life, she's a Mary Sue, introduced as a love interest from the get-go, then shoe-horned into being a regular in a show that has no need for her character on a regular basis. What rubs me wrong most is that for Neal, Kate's been his whole life for years. And then she died and six months later he was in a steady relationship with Sara and the writers didn't think it was totally OOC.

House&Cuddy in House: He's a drug addict and an ass whom the writers twisted into a pretzel to fit him into this relationship, she was a strong woman till she turned into a doormat when she started pining for him. This relationship made me drop the show like a hot potato and I have never properly returned to it.

Gwen&Arthur in Merlin: He's the king, she's a serving girl. I could see her as his mistress but not as the queen. Give me a talking dragon and I'll embrace it. But for a king to marry a smith's daughter to everybody's approval is so far-fetched, even in a fantasy setting, that I just can't root for it. If she were some low nobility or a knight's daughter, fine. But an uneducated serving girl who used to wash Arthur's almost-sister's dirty undies? Yeah, right.

Van Pelt&Rigsby in The Mentalist: He was so in love with her it was pathetic and she said clearly she loved her job more than she loved him, yet she still can't let him go. I really hope that Rigsby stays with that attorney girlfriend of his, she's cute and they fit together perfectly. Yet, I'm afraid that Van Pelt will somehow ruin it.

And the title of the worst couple of all time goes to...

Keller&McKay in SGA: She's a self-conscious damsel in distress who considers him an egoist, he's an arrogant geek old enough to almost be her father. I have no idea how the writers came to the conclusion these two were a good match when they have absolutely nothing in common. They turned Rodney from an arrogant but brilliant man into an insecure love-sick puppy, meek enough to do whatever she demands. Talk about character assassination!
