Marissa Cooper from The O.C
Okay, we’ve got to admit that as teenagers we couldn’t help but be glued to the screen while watching Marissa and Ryan’s dramatic love story but in hindsight, we’ve got to say that she was pretty awful. In fact, even Mischa Barton has admitted that she regrets being on the show. Well, who can blame her?

Marissa was whiny, selfish, annoying, and narcissistic. She also had a tendency to trust bad folks while doubting her true friends. Speaking of friends, she was just awful and put in minimal effort when it came to Summer. Did she even ask her about Seth? Also, let’s not forget that she made Ryan’s life miserable when all he wanted was a little stability.
