It is one of the best Sci-fi movies which I have seen so far, the reason being the mere fact that it tries to portray the potential of a human brain. It is believed that maximum brain usage for a human is around 10% but if one uses it beyond that, what all miracles can it create. Even though acts of Lucy may look very much supernormal to some but indeed I doubt them (I guess one is underestimating the power of brain). Last but not the least the acting by Scarlett Johansson is simply amazing.#mustWatch
