Short version: this is fun!
Slightly longer version: WEREWOLF BY NIGHT is charming and clever, with a combination of old-style classic monster comics and modern twists. But it’s respectful of the former! That’s the cool bit. They could have really messed up and made it stupid; but they did not. I think the people who did the original comics would have loved seeing this.
I don’t really know the people who made this for Marvel, but they did a great job and they should get to do it again, every October.
No, seriously, THIS DOES NOT SUCK.
