Excerpt: "How Do You Know" is a James L. Brooks film that plays like a parody of a James L. Brooks film. It's an overly mannered, emotionally void romantic comedy, ideal for viewers who aren't on the hunt for common sense when it comes to the oily mechanics of love on the silver screen. Straining to coast on charm, the picture instead belly flops immediately, massively overestimating the appeal of the cast and the tender overtones of the script.
Excerpt: "How Do You Know" is a perfect example of how a fine movie is far more than the sum of its parts. The pedigree of the cast and director would have one believe that this could only be a sure thing, but unfortunately for all involved, it falls far short of being anything more than a waste of time and (lots of) money. It's excessively drawn-out and lacks warmth, chemistry and sincerity. So now you know - this film is to be shunned.
