We're drowning in fantastic animation. In the age of Avatar, Kipo and the Age of the Wonderbeasts, Voltron: Legendary Defender, and She-Ra and the Princesses of Power you're easily forgiven the sin of overlooking the excellent 2011 ThunderCats series. After all, it hasn't been on any streaming service as far as I know.
Recently added to Hulu, the 2011 series was planned for 52 episodes but tragically cut in half when the toy sales failed to meet expectations. I don't use the word "tragic" lightly considering how good the 26 episodes were I wish the studio could have finished their tale. I hold no nostalgia for the original series and this series grabbed me by the throat. The stakes are high, the animation fluid, the voice acting is top notch, and the characters draw you in. In the alternate world where the 2011 ThunderCats reached its conclusion, we might praise it as effusively as Avatar: the Last Airbender.
Both ThunderCats (1985) and ThunderCats (2011) are streaming on Hulu right now.
