Self-narration, witty flashbacks and dizzying cinematic visualizations are part of what made this film really enjoyable. While there were plenty of conflicts and adversaries, the lack of a true antagonist or crisis left the plot slightly discombobulated. That much aside, it's more than made up for in clever narration, dark, minor plot twists, a bit of an unresolved ending that is reminiscent of Inception’s, and a fun super-hero/genius feel to the entire film.

“Limitless” has a very appropriate title and is one of the best flicks I’ve seen in a while.
