Within 15 minutes, my whole family was rooting for Goldie Hawn's character to die, or at least for Steve Martin's character to leave her. At 40 minutes, we turned it off. There are only a couple of movies a year we try that turn out so annoying that we can't even stomach it long enough for the story to get established.
Normally I like both Steve Martin and Goldie Hawn, and I remember enjoying the Neil Simon original. So I blame Marc Lawrence and Sam Weisman. Combine the director of "Whats The Worst That Can Happen" and the writer of "Miss Congeniality 2", and I guess this is what we end up with.
