The problem with these kinds of "intelligence boost" plots is that usually despite the fact that the protagonist can suddenly do all manner of crazy stuff because they're super smart, like remember everything they ever read or calculate the outcome of any action and decide on the one most likely to succeed, they still somehow forget / don't think of the most basic shit. For instance, if I was suddenly extremely intelligent and also very well aware of the fact that this was only due to a drug I need to take daily, the very first thing that I would do is make sure my supply is, well, limitless. I'm not even taking the drug and I got stressed out every time I saw him reach into his pill box without thinking about how he would get more. [spoiler]Or, how about the fact that he has absolutely no idea what is in this drug and how it might be affecting his body? Or that the person he got the pills from was murdered by unknown people? Or that appearing in the paper might attract unwanted attention, for instance from other people who are taking the same drug? It just doesn't make sense that he only considers any of these things after 2 months of taking it.[/spoiler]

I thought it was a good ending. I kind of expected it to end with the guy loosing everything he had and either dead or in the insane asylum. While the director tries to stuff the morale of the story that drugs are bad and that in the end they will ruin everything through our throat. Its good to see they stayed clear from that, because that would have been a bad ending.

While the premise is pretty good (a pill is invented that unlocks the power of the brain), make no mistake about it: this movie works because of Bradley Cooper's charisma. In that sense, he reminds me a lot of George Clooney (although one could argue that Cooper makes much better decisions with his scripts). follow me at https://IHATEBadMovies.com
