As you might imagine for the type of movie this is, you're not going to get brilliance. With that in mind, though, the movie is a lot less cheesy than I might have expected.
It's actually fairly realistically written and portrayed. The only thing that strikes me as unrealistic is that the handsome Navy captain would be interested in Lucy, who I found physically and psychologically repulsive. Speaking of which, the mother/daughter conflict would have come across as less one-sided had they made Lucy more sympathetic and not such a frigid, controlling, bitchy spinster.
The only performance that really stands out is Harriet Nelson as the grandmother, Charlotte. Very appealing personality, and her love of sports cars and fast driving was an amusing character quirk.
Jennifer Jason Leigh, on the other hand, is pretty much going through the motions in this role, as in another early-career TV movie she did, "Death Ride to Osaka". But in both cases the material didn't give her the opportunity to do a *whole* lot more.
"Robotech" fans get the opportunity to see voice actor Greg Finley in a walk-on role as a waiter. His natural speaking voice is a lot different from those he did on "Robotech".
Another small role is that of a sailor who I would swear is one of the Estevez/Sheen family, but the credits only mention a Joseph Phelan, who I can only assume is that speaking sailor, not the fighting sailor.
