The interplay of the characters and the dialog make a seemingly trite plot more interesting. I'm impressed with the writing, and the placement and interaction of the various zany characters.
Of course, it does rely on the standard "romantic" plot of two people who start out hating each other and wind up in each others arms. Suspending my disbelief on that old saw, I found the way they got there interesting. I stayed with it to the end, and that's saying something for a guy who won't watch if it gets too "soapy."
