This is one of d greatest time travel films ever made. In all d time travel films that I watched so far, only d hero goes back in time while d rest of d world stays put, which does not make sense, as far would mean dat d same world is being shared by two timelines simultaneously In this film however, when d hero turns d watch, d WHOLE WORLD is reset! The sequence where d villain uses d watch to convince d hero dat he is his father is pure brilliance. As far as I know, this is something dat has never been tried In world cinema ever before, and d creator of this masterpiece therefore deserves a hats-off, for his extremely original ideas and out-of-this-world imagination!
Having lofty aims is not a bad thing at all. The director of 24, Vikram Kumar, clearly did. He set out to create a Disney-style sci-fi film with elements like time-travel, a Stephen Hawking-ish villain and locations inspired by fairy tales. He also managed to incorporate most of those elements. But he then seemed to have remembered that he was making a Tamil film with a really big star in it, which meant he needed to incorporate a lot of other elements. And when you decide to incorporate all those elements, too, you have bitten off more than you can chew.
