One of the better titles from DC's recent batch of animation. "Doom" is likely too violent for the under 12 crowd, but it doesn't suffer from the forced 'edginess' of many of DC's past efforts. The movie showcases a crisply animated, large-scale clash between the Justice League and the Legion of Doom, peppered with just enough character moments that you don't feel like you're watching an 80 minute fight scene.
Has more ambition, drama, violence and characterization than any of the newer DC Comics movies and is therefore more satisfying too. Excellent animation, voice cast and sound too. Worth a look for fans.
