While its feature films may be hit or miss, television series based on DC Comics aren’t slowing down anytime soon.

Today Syfy released a new trailer for the upcoming Krypton show set before the planet’s inevitable destruction. Focusing on Seg-El, the grandfather of Kal-El, better known as the Man of Steel a.k.a. Superman, as he tries to restore his family’s name.
