How Do You Know

'How Do You Know' is the first movie I watched in a San Francisco movie hall.How did I know that's a cool seven and a half bucks I would be losing in the next 2 hours! I was totally flabbergasted by the movie and it's stars. Awesome actors all of them though they well let down by a weak and boring script. It neither engages the actors nor thrills the audience. By the way, what was Jack Nicholson doing in that movie?
