YMMV / Kikai Sentai Zenkaiger Ep 15 The Tubular And Sudden Retro Rewind Kai

• Accidental Aesop: The Kikainoids not falling victim to Retro Wald's major attack, making people nostalgic to the point of lethargy, can be seen as a commentary on racism and people wanting things to go back to the way things were. Just because life was better for some groups (humans) doesn't mean other groups (Kikainoids) remember it fondly. It's subtle and more idealistic as the humans weren't the cause of the Kikainoids' past misery.
