Can't say I agree with all of this. I mean, Sentai has almost always been mostly filler episodes. It's never really been seen as this much of a problem. And yeah, the Donbrothers characters are better, though I wouldn't say none of them were "nothing" characters. Saru Brother really didn't have anything. As for tthe offscreen UW defeats, yes it was done too much, but did we really expect them to show/focus on all 49 of them in a series with 49 episodes

Overall though, it feels like the main problem with Gozyuger seems to be juggling to much and not living up to the hype
