Marvel and DC have been churning out huge cinematic superheroes for the big screen for decades now. While DC certainly had the edge with Richard Donner's Superman and Tim Burton's Batman, Marvel finally got the budget, vision and effects to bring huge franchises like Spider-Man and X-Men onto film. With the release of Iron Man and the shared universe that culminated in The Avengers, Marvel finally got the edge over DC, who - aside from the critical success of The Dark Knight trilogy - is now scrambling to replicate the shared universe template, using Man Of Steel as a platform for finally bringing The Justice League to the big screen. On TV, the superhero genre has been a rather different affair. In many ways it has been around longer - just look at the 60's Batman TV show for example - but it is in the last couple of years that it has really started to take off in the fashion of its big screen counterparts. The CW now have the interconnected Arrow and The Flash, with Legends Of Tomorrow on its way, while ABC is tapping into the shared Marvel Cinematic Universe with Agents Of SHIELD and Agent Carter. But which is better? It is a little less clear cut than the big screen Marvel and DC movies. With less budget, less effects, TV superheroes can feel a little less flashy than Superman or Captain America. But done right, they can make for great entertainment. This article looks at what led up to the likes of The Flash and Agent Carter, what Marvel and DC TV shows are currently airing and ask, on the small screen, who is winning the TV superhero war?
