Flexing different muscles, Marvel's "Werewolf by Night" is a nifty Halloween-timed special designed as a black-and-white homage to the Universal monster movies of the 1930s and '40s. Told with wry humor while tapping into unexplored quadrants of comics lore, it's a bit too gory and scary for younger kids but a gift to fans that raises enticingly monster-ous possibilities.
