Limitless

This movie doesn't exactly go deep with either the moral or thematic implications of super intelligence. Nor are the characters particularly well developed. But I was engaged from beginning to end with this taut and, best of all, original thriller. I've never seen anything quite like it. It proceeds in a generally credible and suspenseful way from its premise--a pill that allows you to use all of your brain.Of course, the notion that we're only using a small fraction of our brains is untrue, but I liked how the film uses this urban fib as a springboard for its engaging story.

There are one or two moments that strain credulity, (I'm thinking, particularly, of the one-eyed thug who can't seem to hit the broad side of a barn with his gun) but I think every good story has a few of those.

The camera tricks and visual effects used to externalize what's going on in the main character's head are also a lot of fun. Good performances by all the actors.

If you yearn for science fiction movies and thrillers that you can actually believe from moment to moment and haven't seen 10 times before, then I'd recommend this one.
