88 of 100.
Pros: Top notch cinematography. Good story concept. DeNiro.
Cons: Loosely ended.
Take a pill to achieve 100% brain utilization. By the way, the pill is addictive, expensive, and dangerous. Also, those who have taken it have not had good overall outcomes. Bradley Cooper plays a loser who also happens to be writing a book. Some would call him a writer. Same thing. He is down on his luck and an old acquaintance steps in and offers him clarity in the form of a pill. After that, the story quickly examines how deep the rabbit hole goes.
I should note, the cinematography is really great from the first opening sequence, and is really shot well throughout the film. It varies just enough every now and then to give the viewer something new and exciting to look at.
The only factor that kept this movie from soaring into the 90 of 100's was the fact that it was ended rather abruptly. I left the theatre with several questions that were not answered, and it wasn't the kind of movie that they would line up a sequel to answer. All in all, I would rent this again. It was a thrilling film, and there should be more creativity like this.
