I didn't like Penny Dreadful much, and refuse to watch any CW show related to DC Comics.
Mostly on priciple, because I think DC sucks. I hate Superman, as a character. Batman is awesome when he's well-written. But it's kind of apples and oranges when it comes to something like a Marvel story. I'm a Marvel fan at heart, so I'm totally biased.
But the powers that be go and try to fuck around with things they shouldn't. Constantine, the show, could have been their start in the right direction, but they took a character that is supposed to be so morally ambiguous that he can talk his way out of hell, and made him cute for network TV.
Weak sauce.
