The pilot is rather good. So I'll give a chance...but we'll see. I agree on Berlanti's DC stuff - it kind of goes down-hill and often rapidly after the first five or six episodes.

Television shows either go uphill after a so-so pilot, or rapidly downhill after a brilliant pilot.

There are a few that kind of float somewhere in the middle.

What bewilders me about the Berlanti DC shows is they appear to be un-killable. They seem to last forever, main cast members can leave and they keep going. And he's able to spin them all off of each other.
