Growing the Beard: Changeman represents a dramatic shift in Super Sentai towards complex plotting, fleshed-out villains, and a Darker And Edgier tone. Changeman's head writer Hirohisa Soda (who'd been head writer for the past three years before Changeman) has stated that he considers Changeman to be a Growing The Beard moment (though not in those exact words) both for the Super Sentai franchise and for his skill as a writer. The nextthreeseasons followed Changeman's example, and all four together could count as a Growing the Beard era.
Special Effects Failure: The mooks in the final battle are depicted by downright horrendous chroma keying, even for the era. Plus the part where the Change Robo is making its way into the core of Bazoo, represented by superimposing mech footage over stock footage of cells dividing.
Tear Jerker: Booba's death in Episode 52, just moments after he restored Shiima to her former self.
