I wonder how much of it is on Sakamoto, though. Clearly the writer must have had some hand in it. I mean, Sakamoto portrayed cute lovey-dovey rage monster, and I can't imagine cute lovey-dovey rage monster wasn't what the writer intended.
No, I'd argue this is definitely Sakamoto here, given how Toei has pretty much made no illusions, hell outright admitting it in Akibaranger, about deliberately pander to Koichi Sakamoto in any of the productions he's been part of (and I still distinctively remember the producer admitting to hire Amy's 16 year old actress for Sakamoto to ogle at).
Everything Sakamoto has ever had any part in, there will always be exactly two types of important male characters, which is either the generically cool "manly" guy who can do no wrong and the arrogant/cowardly guy who has to learn lessons from the cool manly guy, which then in turn forms a major arc in the story.
Everything he's ever involved in it has always been the same macho, hyper-individualistic narrative, where everyone don't just listen but surrender to the big dick because his way is always the correct one.
The only times this has pretty much been tolerable, even worked, was with Fourze and his Ultraman stuff, but I attributed that to the writers Kazuki Nakashima and Keiichi Hasegawa, and the general fact that Tsubaraya still likes keep some level of integrity and heart with Ultraman more than Toei does with Kamen Rider.
Of course, it doesn't help that all the female characters... Okay let's just put it bluntly here, are basically there to be masturbation fantasy. This is not even up to question, this man has shown nigh absolute incapability of keeping it to himself, and proven to be nothing but chauvinistic as all ****. Women are either outright nuisances or cool only if they are also sexy in miniskirts, the worst in either spectrum being the shitty treatment of Akiko in Accel movie and the existence of Kamen Rider Nadeshiko. Its absolutely disgusting, added up to the prior fetish for immature Great Man stories.
(Then again, I suppose to be fair, not every problem in Kyoryuger can just be blamed on Sakamoto, given the presence of Riku Sanjo and Takahito Ohmori, who are enablers to a disgusting degree.)
