The presentation is epic in intent, yes. Alas, the execution, packaging and projection leave the epic undernourished and over-emphasized.
The magic of animation cinema is to transport the audience into the world of make-believe, but in a way that we forget the characters are not real people. In other words, for animation to be effective, the narration must transcend the technique of animation.
Mahabharat, as told by director Amaan Khan, never goes beyond self-congratulation. The animation characters are so busy posturing they are never humanized. All we see are graphics, not the spectacular characters from the Mahabharat whom we've grown up with. We hear them. But they never attain credible shapes on screen.
Incidentally, Draupadi's vastrahan scene has to be seen for us to know how clumsily inadequate the animation and graphics are. The saree doesn't unfurl. It ties itself up in knots, in a manner of speaking.
There is a laboured attempt here to prove that animation has come to animated life in Indian cinema. Sadly, it ends up proving only the opposite. We've a long way to go. If you want to see a credible dramatically deft adaptation of the Mahabharat, check out B R Chopra's televised version.
As for animation, I suggest Indian cinema leave it alone.
