If you would like to see the range of opinion among film critics on "The DaVinci Code," one very nice inventory of major-media reviews can be found at metacritic.com. It earned a 48 out of 100, well below this weekend's new cartoon, "Over the Hedge," which averaged out to 67.
For a comparison, you can see that "The Passion of the Christ" averaged just about the same, a 47.
