A caper flick with a narrative so arbitrary, scattered and disjointed, it’s like an intermittently entertaining prank is being played on the audience.
For its protagonist, it’s a vivid dream that provides an escape from a terrifying reality. For the audience, it’s a grating grab bag of titillating nonsense. For a critic, it’s a session with a doodle pad.
“Limitless” is an admittedly limited but fascinating what-if thriller, a pharmaceutical fantasy about being all you can be without joining the military.
