Based on the original 1960s TV series, we see Batman and The Boy Wonder fight it out against some of their most famous foes. Not only that, some of the characters are played, at least in voice, by the same people who played them soo many decades ago. Even the original Catwoman, Julie Newmar appears!
It looks a very silly look back of the classic series. On the other hand, the animation style also looks like it was made in the mid 1990s not the mid 2010s. It has the X-men feel to it.
It’s back to the 1960s as Batman and Robin spring into action when Gotham City is threatened by Batman’s most-evil opponents – The Penguin, The Joker, Riddler and Catwoman. The four Super-Villains have combined their wicked talents to hatch a plot so nefarious that the Dynamic Duo will need to go to outer space (and back) to foil their arch enemies and restore order in Gotham City.
