chick flicks are basically romantic comedies.
action does not qualify...
this means that Tomb Raider is not a chick flick.
however, there are certain romantic comedies that are not chick flicks because they are so good they rise above.
Notting Hill, Pretty Woman, My Best Friend's Wedding are a few...hmmm...the Julia Roberts factor
Sleepless in Seattle is not a chick flick...it is a damn fine movie.
etc...
Steel Magnolias is a chick flick
so is Ever After...although I do kinda like it.
any old flick starring Audrey Hepburn is a chick flick.
of course that could just mean that I'm gay.
