It's maybe unusual, but I wouldn't worry about it. I love movies- not guy movies and not girl movies but MOVIES- some I like because they are acknowledged classics and some I like because they just strike a chord in me- one of my favourite 'chick flicks' is 'The Truth About Cats and Dogs'- I think it's a good movie but I also like it because I used to love the T.V. series 'Game On' and I thought that Ben Chaplin was a very funny guy, and I've always had a sneaky wee crush on Janine Garofalo. Don't worry about any loser who says that it's 'gay' to like chick flicks- it says more about them than you. Besides, 'Notting Hill' was a much better movie than 'Four Weddings'.
Interesting aside- one of the coolest thing about my wife it that her favourite movie of all time is 'Full Metal Jacket.'
