Euro-schlock producer Luc Besson latches on to and runs with the debunked urban legend that humans use only ten percent of their brains’s capacities. The result is a pulpy, preposterous, action-packed yet mildly contemplative and never predictable blend of 2001 and Charly, with a dash of The Matrix. Pseudo-science aside, it also happens to be a total blast. Does a superb job of feigning depth. Scarlett Johansson’s spot-on in the title role of a party girl forcibly drafted as a drug mule who suffers a massive dose of a new mind-expanding drug and turns into an existential superhero. Insanely fun. (90 min)
