Following in the footsteps of Lego Indiana Jones, Lego Batman is based on the Michael Keaton, Val Kilmer films, at least from a soundtrack and character point of view as the missions bear no relation to any of the films.
As with Lego Indy, the cut scenes are humerous and the gameplay hasn't changed so those who have played the Indy or Star Wars games will feel right at home with the controls.
As always, you can only fully complete the game when playing in Free mode as after completing the main 15 levels in story mode you'll find you haven't even completed a third of the game.
Little kids will love it, big kids too. It's easy and fun for everyone. I wonder what's next... Lego Justice League maybe?
