Even though I'm still looking forward to Star vs. the Forces of Evil more, this is a nice little show to hold me over. It's essentially Quantum Leap or Sliders for kids in which the main character and two of his friends temporarily possess the heroes of other dimensions to fight off the villain and his idiot sidekick (who is also the kids' school principal) who have possessed that dimension's main villains. A lot of guest voices appear like Henry Winkler and even Adam West, too. Penn Zero is strictly formula, but I'm hoping they play with it and twist it like Phineas & Ferb does to keep it from getting stale. Plus, the multiple dimension angle offers a lot of creative possibilities for worlds.
