These are the only ones I think are worthy of talking about... right now...
Bridget Jones' Diary - I still cringe much of the time because I refuse to believe this character could be anyone in real life, but its still cute. Plus, Colin Firth... "I like you... just the way you are."
America's Sweetheart -

- I think I'm the first one to mention this one, but I've always enjoyed watching it. And I have a thing for John Cusack...
Shakespeare In Love - I first rented this movie from the library when I was in 4th grade, and enjoyed it until... I caught sight of Gwyneth Paltrow's boob. I quickly turned off the television and felt like I loss whatever innocence or purity I had in me... almost guilty or ashamed.

But, a couple years later, (after I grew up a little) I enjoyed it and plus, it opened me up to Shakespeare... BTW, if they left the original scence shown in the special features, I would have detested this film.
Eternal Sunshine of the Spotless Mind - One of those films I didn't think of as a "chick flick." - How can anyone not love this film? Such great writing and performances.
