There have still been a few voices expressing a degree of disappointment, positing that this would have been better had the DC movies and the DC television series been unified; that the story we see on Arrow and suchlike would follow the story we see in movies such as Man of Steel, Batman vs Superman, and the upcoming Suicide Squad movie. It’s a model that Marvel employs, with their Avengers movies being set in the same universe as their Netflix programmes such as Daredevil or Jessica Jones; it’s in part because of this that people would like DC to have followed the same model.
Most immediately, there’s the matter of granting the programmes (because movies would undoubtedly take precedence) a level of freedom to chart their own path. The DC movie universe has, rightly or wrongly, thus far opted for a much darker interpretation of their iconic heroes; one that’s entirely valid, of course, but one that’s also worlds away from the lighthearted, even campy, tone of programs like The Flash or Legends of Tomorrow. Keeping the universes separate allows for both the movies and the television shows to have a greater level of control over their own direction and progress. Indeed, this was the same logic behind the choice when Zack Snyder committed to not using Grant Gustin’s Flash in the Justice League movie.
This article is in fact from late last week, I’m only just getting around to posting it on my personal blog now. It’s discussing the different DC universes, and why – ultimately – I’m actually rather glad that Warner Bros. decided to take the route of a multiverse rather than a shared universe. (Even if they didn’t approach it in those terms!)
