The new Starz drama "Da Vinci's Demons'' might turn out to be a decent series, although you'd never know if from the debut a confusing mess more notable for the full-frontal nudity than the plot. But Episode 2 of this series that casts Leonardo Da Vinci as a genius/action hero is more coherent and considerably more promising.
