We now live in an age dominated by shared film universes. In fact, there are 12 of them in active development at the time of this writing. The most successful of all these being the Marvel Cinematic Universe which started its life back in 2008 with the intention of bringing the comic book publisher's flagship characters together on the big screen. Years of careful planning and attention to detail made it one of Hollywood's most commercially successful and critically-acclaimed franchises of all time. It only makes sense for competing studios to capitalize on its success by creating their own.
Time Warner, owner of Warner Bros. and DC Comics, is one of these companies. After Batman's widely successful outing in The Dark Knight trilogy, they released two films, Man of Steel (2013) and Batman v Superman: Dawn of Justice (2016), that signaled the beginning of the DC Extended Universe. The only problem is, both movies have received mixed to negative reviews from critics, scoring a "rotten" rating from review aggregator Rotten Tomatoes.
It is not too late for DC to recover from this. After all, box office returns will more than make up for the production and advertising costs, thanks to the lead heroes' loyal and dedicated fan base. Additionally, audience reactions to the trailer of the universe's third installment, Suicide Squad (2016) seems to be promising.
So what's next? I believe things would improve dramatically if DC was given their own filmmaking arm that would produce nothing but films and shows based on DC Comics properties—think DC Studios with Bruce Timm as president, Paul Dini as co-president and Geoff Johns as creative director. Such a division would allow them to exhibit creative freedom, control and focus on potential projects in their portfolio.
Warner Bros. just can't afford to give the DCEU the attention it demands at its current state. They have too many projects on their plate and too many cooks in the kitchen. It's so crowded and convoluted.
