I at least commend it for trying something different with the secret identity element. But let's face it, no one was clamoring for this one. I remember thinking the idea of Ridley Scott/Russell Crowe working on a Robin Hood collaboration sounded cool to me when first announced. We know how that turned out.
This is one legend which has been done to death. I really like Prince of Thieves. Errol Flynn version is a definitive classic. Disney live action film from the 50s and the funny animated one with Ustinov, Terry Thomas, and Phil Harris chewing the scenery are very solid. But how many times are they going to go to the well with that story.
Didn't see this new version but trailer reeked of trying to make the story fresh for the modern audience.
