Zyuohger would be closer to like 20 if I were to rank the series. The villains were just dreadful and so god damn boring. I would rather rewatch Ohranger or Liveman over Zyuohger because despite those series' flaws, their villains have good arcs and moments. Plus, Ohranger has some truly epic episodes whereas Zyuohger's were average to below average. I wasn't wowed by anything they did. Oh, and the Gaiarks could have just been wallpaper and they would have gotten the same effect.
