Bradley Cooper gets to do some crazed, substantial acting in this, the story of Eddie Morra, a man suffering from writer’s block who is able to access 100 percent of his brain thanks to a mystery pill. The film isn’t so much a deep rumination on what would happen to a human if they could access their whole brain as it is a shallow yet snappy thriller. Cooper is great fun in the lead role, which definitely has a humorous side. And Robert De Niro does some of his best work in years as a business tycoon who takes a shine to Eddie when he’s on the miracle drug. Director Neil Burger has made a fun movie that could’ve been great had it gone a little deeper. Still, it’s worth the watch.
