An interesting concept about a guy taking a drug that enables him to use 100% of his brain at all times. Nice idea which isn't really brought across fully in my opinion as the film just seems to lack a kick. The story seems to wander across a few sub plots which don't really get explained too well and I found myself asking how did that happen? when did that happen? where did he get that? and why did he do that? Too many little moments like that happen throughout. Of course the whole idea about humans not using 100% of their brains is complete nonsense. Over the course of a day we apparently use virtually all of our brain power, not all at once of course but spread out, as one section fires up another cools down like any machine. So this fantasy is just that...a nice fantasy but a cool one. Yes the whole plot is quite neat but made in an unoriginal way. The guy starts off as a nobody but after taking the drug he is able to cheat life and get lots of money, girls, material things and a certain amount of power. Its a basic concept that has been done before, not entirely in this way of course but its a simple rags to riches tale really, very predictable. The acting from the main cast is stellar as you would expect which in turn really makes you believe what's going down, its definitely a thrilling ride. As the film progresses it does get quite tense as Cooper runs out of drugs, he has the mob after him for more whilst De Niro wants his big money deal sorted. It does get your palms sweaty for sure, you feel the tension. There is some interesting camera work showing the effect of the drug, from a virtually dull black and white existence before to an almost bluray sharp pixel perfect colour burst once the drug is taken. A glorious visual feast that gives you an explosive sense of being high or alive for the first time. You can feel the characters sense of invigoration and liberation upon taking the drug, when it hits. What I didn't like was as the film progresses the people that take the drug go from being sort of super intelligent to also being a little super human too. When the effects start to weaken or they need the drug in a dangerous situation they just pop a pill and bingo! they're kinda super human again. They seem to be able to fight, run, leap, practically anything really which kinda spoils to idea, it goes overboard a bit. The ending spoils the film too as Morra (Cooper) ingests the drug in a rather stupid and unrealistic way by lapping infected blood up off the floor from a recently dispatched baddie. That really seems like a rather dodgy thing to do surely, you could pick up anything young man! Plus there are more odd questionable moments along the way with a weak finale that again leaves you thinking wut?! What does spring to mind is if this drug is so good and controllable, why doesn't everyone, mainly Van Loon (De Niro) just take the drugs themselves instead of relying on Morra for results. Too many questions for me.
