YMMV / The Adventures of Batman & Robin E19 "Deep Freeze"

• Complete Monster: Grant Walker is a seemingly affable theme park mogul who seeks only to prolong his life by way of Mr. Freeze's ice technology, but in truth harbors much darker intentions. Kidnapping Freeze and using his comatose wife as a bargaining chip to convince Freeze to give Walker his icy, undying condition, Walker soon enough reveals his plan to use a massive freeze cannon to plunge the entire world into a new Ice Age for years. Walker hopes to kill off all of humanity except for his "chosen few", then repopulate the planet with his own Garden of Eden, and though his plan is foiled, Walker returns in The Batman Adventures, where he kidnaps several scientists to cure himself of a lethal condition, planning to kill them all and then restart his scheme to wipe out humankind.
• Harsher in Hindsight: Mr. Freeze is horrified by Grant Walker's desire to be like him, knowing that while he desires only to revive his wife, all Walker cares about is his warped idea for a perfect world. Then came New 52, a contested reboot of the DC Comics universe where one of many controversial changes made was that they retconned Mr. Freeze's origin so that Nora was never his wife, rendering him just another psychopath with no redeeming qualities. What's worse is that Mr. Freeze's wife Nora originated in the DCAU before she was incorporated into Freeze's backstory in the comics, so the New 52 Mr. Freeze having that aspect of his origin stripped of its humanizing qualities can be seen as a slap to the face of the incarnation that made Mr. Freeze a popular villain in the first place.
• Hilarious in Hindsight:
  • One of the toy robots Karl Rossum shows Batman and Robin when they visit him resembles the Silver Age version of Mr. Mxyzptlk. When the real Mxyzptlk actually appears in Superman: The Animated Series, he looks nothing like his Silver Age design.
  • This episode could be titled "Batman predicted BioShock" due to the similarities between both stories and setting. A rich, ambitious, Objectivist magnate reminiscent of Walt Disney creates an Art Deco Underwater City for him and those he invites to escape the corrupt surface world. There, he and his fellow members create a plethora of advanced robotics and genetic engineering that inevitably results in the end of the city and its founder.
