"The Almighty Johnsons" is a low-wattage take on Norse mythology from New Zealand, which does away with extraordinary powers and godly might to focus on the daily bouts of melodrama facing a band of four brothers and their grandfather as they learn to cope with their secret lives. The program is an acquired taste, with the first season (the show was recently canceled after its third year) devoted to convincing the viewer that names such as Odin, Thor, and Loki could embrace a different interpretation in the Marvel Comics world we live in. Instead of power and brawn, "The Almighty Johnsons" takes on the foibles of relationships as it pays vague attention to the magical forces that run the universe, submitting weak jokes and feeble conflicts as it works to define its creative mission in ten episodes.
