Be sure to check your sense of reason and reality at the door; unlike the DaVinci Code, this installment is no where near being as believable and plausible, still the ride is fun, with intrigue and action from the first few moments going through the end of the film with the predictable 3rd-act twist.
As usual, Tom Hanks chews the scenery and make no secret that he wants the cameras focusing on him, and only him during most of the film. No doubt he would have preferred having a steady shot of him during the entire film, but that pesky story line gets in the way.
