The contrast between Dynazenon and Back Arrow is there.
Back Arrow fully embraces being a classic-style mecha show with a straight face while Dynazenon (and Gridman) tries to do the monster of the week formula that focuses on semi-realistic, relatable human drama while the elements that make a mecha/toku show interesting are mostly ignored, are a backdrop, or simply just flashy fights to remind you you're watching an action series.
Such a waste of a great robot design.
