At first when I started watching this film, I got pretty scared, because in act 1 it was almost an 80% match for a project I'd been working on for years, called transparency filter. For a minute, I thought someone had beat me to the punch, and all my work was gone.
Then came act 2 and 3. After thinking through where this scenario would likely go, this film appeared as a dud firework. I really liked it, don't get me wrong. It's just that they took an idea that could be as epic as star wars, and turned it into something that happens between a few people in a neighborhood. Take an idea that could would undoubtedly change the course of human history, and have it culminate into a guy with a bat chasing the protagonist? I'm sort of questioning if the writers need some of their own fictitious pills.
For those that are younger, these type plotlines originate primarily from Daniel Keys famous novel "Flowers for Algernon" which was at one point made into the film "Charlie". Ultimately, you'd probably enjoy Limitless more, but there's a movie coming in the future that takes this concept to a whole new level....
