Spite isn't a good enough reason to go see a Julia Roberts movie, although I sympathize with you.
Just wanted to assure you that anyone with reasonable taste will not consider seeing this movie sitting next to their friend, neighbor, spouse or date. It is probably a cheap way to avoid the internet sex chat charges though and get popcorn to boot for those who prefer shock theater as opposed to the true art of theater. There will be plenty that go that will think twice about seeing another movie of hers.
