From NetFlix:

With his writing career dragging and his girlfriend casting him off, Eddie Morra’s life turns around when he takes a drug that provides astonishing mental focus — but its deadly side effects threaten his future.

Seemingly slow at first, this imaginative and clever plot takes off and the suspense never ends. While the acting is nothing special, Bradley Cooper and Robert De Niro are acceptable. But it is really the roller-coaster sequence of action scenes that make the film fun to watch. Without spoiling anything, you can expect separate situations for Cooper and for his girlfriend Abbie Cornish in which they are cornered by one or more of the “bad guys” and they swallow a pill containing NZT and “Shazam!” they escape with a wonderfully contrived solution.

Of course there is a lot of violence and some possibly disturbing scenes.

Although the ending seemed too good to be true, I really recommend this film as a fun few hours of escape.
