10-year-old Billy Batson shouts a single word and, with lightning bolts flashing, he transforms into Shazam!, a full-fledged adult Super Hero. It doesn't take long for Superman, Wonder Woman, Batman and the rest of the Justice League to take notice and invite the earnest do-gooder to join the team. But to become a member, Billy must reveal his true identity. While fighting off the evil Mr. Mind and Black Adam, Billy learns that he must trust others - and that nothing creates trust like helping those in need.
The Lego DC Universe has a new superhero, Shazam. After he helps the Justice League at the Metropolis Farmers' Market, the group invites him, however, he refuses, as he his afraid to show his true identity due to being a kid and they will reject him for it. However, after the League falls for a trap laid by Mister Mind, leader of the Monster Society of Evil, and regressed to kids so he can easily mind control them, Batman manages to escape, and now, he and Shazam must trust each other to save the others, as they are brainwashed to bring Mister Mind food.
This is a good DTV film. The film is basically a lesson in trust, as Shazam has to learn to trust other with his secret, despite his fear of how the other heroes would react to him being a kid. Also, the story is good, the voice acting is great, and the action and humor are done greatly. I recommend this one for younger superhero fans or fans of Lego in general.
