That said, there are 'chick flicks' I really love: Return to Me, Notting Hill, You've Got Mail, Sweet Home Alabama, Sleepless in Seattle, and so on. They really don't make great chick flicks anymore - with average looking people (Tom Hanks? No one would call him a heart throb but everyone LOVES his chick flicks...) having average interactions that could be a little more plausible than, well, your dead husband leaving you notes every month (or so?) for a year until you get over it. It's a lovely thought... but it creates a false expectation.
I don't watch chick flicks often for a few reasons - I think it's really hard to do a good chick flick, I think it's a fine line between complete cheesy cliches and plausible scenarios (500 Days of Summer - excellent), and it creates false hopes and expectations of real life relationships or scenarios that are truly a rarity if every happening. We would like them to happen. We'd like to dream that that proud British rich man actually has a heart of gold and has fallen in love with you with the mere exchange of some witty remarks and sarcasm (oh yes, I did it) and despite your eternal vow to loathe him, find yourself loving him too as he constantly redeems himself and builds a perfect facade of exactly everything you've wanted your whole life. It's a pretty picture... but then the credits roll... and you're back to your day to day living, but now with a little bug planted in your subconscious telling you "someday your prince will come..." And he will, just perhaps not on a white horse with tickets to that thing you like (now there's a great commercial).
