I know nothing of the comic, but the show has some promise. The pilot was a bit rough around the edges - could tell the writers were challenged on how to cram the whole backstory into the first episode to get the audience up to speed. I'll wait to see if it becomes a bit more focused in the next few episodes where it seems like he'll have more of a "team".
I must admit, I thought it quite humorous near the beginning where the girl just witnesses the ground opening up and fire spewing from the Earth, then freaks out and grabs a can of mace when a guy steps out of a taxi and offers to help her. Yeah, that's what she should be afraid of...<face palm>
