Strangely, one of my favorite films with O'Neal.
It reminds me of "Whales of August" in some ways, the two sisters trying to determine what to do with rest of their lives. I remember especially at the time that it seemed very unconventional for her love interest to be non-causian, besides being blue-collar.
Usually not my cup of tea but I remember yelling "Yea!" when she left to live her life beyond her sister's thumb and taking a chance on love.
