Almost but no cigar. It was beyond exciting to discover we'd be getting an animated Justice League series after so long without one but having been raised on the efforts of the DCAU, it's devastating to witness the fall from glory.
I would have to say that Young Justice has been the closest thing to a genuine DCAU product since the mid 2000s but we all know that one's fate - mired by lackluster toy sales. That is the conundrum. Many of us seek the mature themes and darker tones of the DCAU in our animation but sadly we are not the same individuals buying the toys. So long as toy sales are essential to the success of an animated property, it's safe to say that shows like Teen Titans Go and Justice League Action are as deep and rich as it's going to get.
All of that said- what does this tell us about the show itself you ask? Well for what it's worth, they do live up to the "action" portion of the title. Episodes are remarkably brief (11-minute shorts) with minimal character development and simply by-the-numbers plots. Thief makes off with artifact, Batman and Green Arrow thwart thief and return stolen item. Sadly, it isn't going to go much deeper than this.
There are chase and brawl sequences aplenty, however, and after a time the simplistic visuals and flat color pallets don't look so bad. fortunately they kept the voices of many of the iconic actors from the DCAU days. That helps immensely in not making this feel like the red-headed stepchild of the "real" earlier versions of these properties.
All in all, kids today will likely enjoy the show well enough, this having been their prime exposure to the characters in question but those of us a bit older, who grew up on Batman The Animated Series, Superman The Animated Series, Batman Beyond, Justice League and Justice League Unlimited, we're left with the daunting reality that there will likely never be a return to former glory. I suppose the only consolation there is that as today's audience matures, perhaps they can hunt down these classics on DVD/ blu and discover the magic for themselves.
Marvel has always had DC beat on the big screen but DC owned it in the animation department. This is becoming less and less the case with each passing season.
