Basic rules of a chick flick
Rule 1: There is no such thing as a sci-fi or horror chick flick. While fantasy can certainly be used in the storyline, movies that are dominated by technology and gore cannot be a chick flick.
Rule 2: A film cannot be a chick flick if the female goes to the movie to see her favourite male star, regardless of the content of the movie. Therefore female fans that went to see ‘Troy’ just to see Brad Pitt means that ‘Troy’ isn’t a chick flick.
Rule 3: A true chick flick cannot be a full-on comedy. For example "How to Lose a Guy in 10 Days." It fits many of the criteria of a chick flick. The same may be said for Legally Blonde I and II.
So, what are the conventions of a chick flick?
1. The female lead must be a strong woman who faces adversity and overcomes it, usually by pure force of will.
2. There must be significant tragedy that the woman must overcome to reach her stronger self. In its simplest form, someone has to die, often the lead female, herself. Pretty Woman is the exception that does not prove this rule.
3. There must a love interest.
4. There may be no violence, war or fight scenes in a Chick Flick
5. There must be at least one moment where a character cries. The shedding of tears may be of sadness or happiness, but there must be crying.
