I love a good chick flick. I love the nascent flirtations, the beginnings of romance, the inklings that someone would be specifically designed for someone else. I love the concept of soulmates.
There's another reason that I love a good chick flick. It's the reason that I can watch ridiculous teen dramas (e.g. The O.C., Gilmore Girls, Gossip Girl) back to back as un-ironically as possible; a chick flick is predictable, formulaic even. It's like a warm cup of cocoa on a cold winter's night. I'll give you an example:
A boy meets girl, but something comes in between their love. Perhaps they are business enemies (You've Got Mail), they are from different classes (Ever After), or perhaps it just takes them forever to figure out they love each other (Clueless, He's Just Not That Into You). Then comes some drama, maybe he professes his unrequited love (Pride and Prejudice), he decides to marry someone else (Made of Honor, My Best Friend's Wedding), or he tries to arrest you for murdering your sister's creepy boyfriend and then bringing him back to life and killing him again (Practical Magic). Despite it all, they will get together in the end (expect for the crappy chick flicks in which they won't get together) and we live happily ever after.
See what I'm saying, it's like an old comfortable pair of pants you've worn in perfectly and will never get rid of, even though they stopped looking cute years ago.
