Limitless is an American comedy-drama television series (2015) based on the 2011 film of the same name,
It stars Jake McDorman as Brian Finch, burnout and struggling musician, who discovers the power of a mysterious nootropic drug by the name of NZT-48.
This drug unlocks the full potential of the human brain and gives its user enhanced mental faculties.
Though it only lasted one season, I thoroughly enjoyed every minute. Very funny. And great special effects.
Bradley Cooper has a small role, so he must have thought it had potential.
To tell the truth, it was Jennifer Carpenter who I likde best.

I watched all 8 seasons of Dexter. Jennifer played the serial killer’s sister. And later married him in real life.
