What: A teenager (Robbie Amell) discovers he's the next step in human evolution thanks to the help of others like him.
Why: Last year's biggest action hit, Arrow, featured an Amell on The CW and it appears history will repeat itself this fall. The potential for this super-powered series is limitless -- as is, apparently, the creativity possessed by producers Greg Berlanti and Julie Plec, who undoubtedly have another hit on their hands.
When: Wednesdays at 9 p.m. on The CW.
