By its very nature, The Whole Truth requires a reveal at the end – the final confirmation of how the murder actually took place. The unfortunate part of this requirement is that the reveal is not a surprise; that The Whole Truth doesn't have anything truly special up its sleeve. It is a letdown in a film which is otherwise a tense courtroom thriller. The movie tips its hand just a little too much a little too often, which takes what could be an exceptionally satisfying thriller and turns it into an acceptable one. It is a film which succeeds based upon the acting and sense of tension it imparts, but those elements never work in concert with the story.
