If you have seen Lucy, you have seen this movie. The endings and the gender of the main characters are different, but the story is essentially the same. There’s a pill/drug that allows the user to tap into his/her full brain capacity, making them smarter, faster, limitless. However, with great power and ability, come great hurdles.
I recommend this over Lucy. The Limitless story was coherent and plausible whereas Lucy lost track of it story and became more ridiculous as the movie continued. I really liked how Bradley Cooper’s character had a very Matt Damon-esque quality from Good Will Hunting when winning over people. All things were so eloquently spoken and pretentious.
