Gone With The Wind
These two characters are so toxic that it's shocking they kissed instead of broke up! Maybe back in the day, they were considered romantic, but in 2020... not so much. After all, Scarlett loves someone else throughout the entire film, so the kiss was most definitely a surprise.
Grease
Grease is such a fantasy movie that their relationship would never work in the real world. They're totally wrong for each other, especially since Sandy had to change herself to be with Danny. Oh, well, at least those fans got the kiss that they wanted!
