Well-written and thrillingly acted.

Rating: 8/10 (27 March 2011)

One of the most endearing surprises of the year. What this film does is take an original premise, and turns it on it's head in ways I never thought possible. I enjoyed this flick from the opening scenes which let's the audience(finally) to get into the main character's head and strangely enough, we end up rooting for him as his life is constantly in danger from unknown assailants and to a greater extent, himself. That's what makes the narrative arc of this film so compelling. The drug itself is simple yet detailed enough to be explained to any interested viewer. On top of that, what makes this film so refreshing is that there's no huge explosions and gratuitous sex scenes that are so prevalent in Hollywood films. In fact this film is almost an anti-Hollywood film and that in this day and age is a MAJOR plus. If you want to see a well-written and thrillingly acted film, see "Limitless". One of the best thrillers I've seen this year.
