Truthfully, this is a welcome variation on The Ugly Duckling scenario (TM pending), if only because Hollywood usually reserves it for stars like Lea Michele, who is constantly told on Glee that she isn't hot. (Ahem.)
Anyway, we're getting off track. Limitless
Meanwhile, a bigger question: What's with the use of Kanye West's "Power" at the end of this thing? Just because The Social Network got away with that, doesn't mean you can, Limitless! Yet, with all that said, this looks like it will at least be worth a click to the top of the Netflix queue. Or at least a perusal of the IMDb user boards to find out how exactly Limitless ends.
VERDICT: Passable.
