Honestly, I think Toei's suffering now from not having a third franchise going. A lot of the staffers who reinvigorated Sentai in the 90s cut their teeth on Metal Hero and Fushigi Comedy, and had time to work the kinks out of their creative styles before moving to a higher-profile series.
I wonder if part of the problem is also a lack of any real competition in the same field to motivate them. Both Toho and Takara's attempts to make their own Toku shows in the 2000s died out after their third series so, past a certain point, there's been no real need to innovate to keep up with anyone else.
It's sort of like that weird place Nintendo fell into when Sega was dying and Sony had not yet fully developed as a competitor. (And I guess Go-Busters is the Virtual Boy equivalent in this analogy.)
I do wonder if, much like Sony, if Super Sentai continues this downward trend, others might start getting frisky again at the idea of trying to knock Toei off its perch.
Well, geez, there's not a Gokaiger episode that even gets into the same ballpark of bad as the stupid Goseiger cheerleading episode.
I'd argue pretty much all of the Don focus episodes (including the ones he steals away from Aihm) are even worse than the cheerleading episode. While the cheerleading episode is certainly, unarguably dumb-as-balls, you can forget about it and move on when it's over since it never comes up again.
However, Don's issues of being a spineless whiner who needs to MAN UP keep reoccurring every single time the camera swings back around to him so you get the same dumb-as-balls episode every single time.
In a series that's nominally supposed to be about learning from your elders while becoming your own man, the fact that Don so aggressively reverts back to step one just highlights the fact that anything the older teams are telling him are instantly forgotten once the episode ends.
Heck, the "aggressively reverts to step one" problem is pretty much one all the main five have.
The Jetman episode is about the biggest poser in Sentai history coming back from DEATH ITSELF to tell Marvelous, "Hey, stop being a poser like I was!"
The very next episode? Marvelous is right back to being the same kind of poser he was all along and will be until the final episode.
It honestly makes the show FAR more aggravating to follow than Goseiger because having the occasional dumb-as-balls episode is annoying but Gokaiger's tendency to accidentally stumble onto something interesting and then ACTIVELY RUN AWAY FROM IT every single time is outright infuriating.
It's also just a bit weird how much of Goseiger's acting/appearance flaws are so immensely exaggerated whenever the topic gets brought up and yet the Gokaiger's are just kind of ignored or glossed over.
What is it that allows people to forgive Marvelous' inability to make an expression other than "I have very bad gas" and have absolutely no change to his tone of voice at all despite whatever mood the script calls for him to have but not Agri's "be really stiff and bare teeth in a weird, inappropriate way but generally get the idea of what emotion he's SUPPOSED to be experiencing through his tone of voice"?
