Sandra Bullock and Nicole Kidman are perfect in it and it's nice to watch Stockard Channing and Dianne Wiest (Parenthood) in costumes.
I'm only giving it 4 stars because there is a scene in it where they poke a pigeon with something sharp during a spell(they don't show it, but it's clearly implied). I don't like to watch any animal being hurt and it urked me. Sooo Hollywood! You shouldn't be hurting anybody/anything for a spell--can only bring bad karma.
Otherwise, it's an entertaining movie :)
