Me neither. But it helps that executive producer Marc Guggenheim wrote for DC before this. That may be a first for a live action show. We had comic writers write a few episodes, but never in such important producing role from its inception.
I am happy in particular with the Royal Flush Gang. Its such a simple concept in terms of playing card theme for criminals. Anyone who never heard of the comic characters will get it. Even the name, being a gang is very modern and timeless sounding.
