So we watched 'Vixen', CW Seed's exclusive web series 'Vixen'.  Compelling female superhero origin? Check. Crossover with well-known established 'Arrow' and 'The Flash' universe characters? Check. Introduction to magic in said universe? Check.  But what of execution?  Did Arrow and Flash come off correctly (even with Stephen Amell and Grant Gustin providing voice work)?  Was there enough meat and potatoes in the six five-minute episodes to make it truly satisfying, or was this just an awkward first look at what could become a truly cool character within the mythos of the CW 'verse?
