Lucy was really good. I did think that she was gonna become a superhero though. It keeps you interested in the story and is very entertaining. I liked Lucy. Scarlett Johansson knows how to kick some butt. She is good at what she does. It has some action but nothing that goes BOOM!! I also liked Morgan Freeman. He is also good at what he does. He is funny person but we he needs to be he can be serious. The story was great and shows an interesting way of how to use more of your brain than we do now. I didn't even know that we use less than 20% capacity of our brain or even had more knowledge in our brain that we don't know about. It is a movie that may be a must see for a second time kind of movie.
