Two teens from rival families fall in love… it doesn't go well.
I agree with brooke. It comes close to Snyder’s example of the logline “She was the perfect date… until she had a drink” in that it makes you imagine a whole lot that could go on which is great. Maybe it just needs a little context, i.e. what area are the families rivals in? Are they bikies? Mafia? Keeping up with the Jones’ type neighbors? Just a little more information would make a big difference. The mention of a twist of some kind on the old Romeo and Juliet plot might help too. Good start.
