Another Zi-O II Watch is now a Deus Ex-Machina that can reverse time without ever being used to transform to revert Tsukasa back from the dead (which was a pointless scene).
The only two characters I liked from Drive was Chase and Heart, and them bringing him back here was nice, but again, it's kind of inconsequential. Doesn't matter what they do with him in the next episode, they could have done that on a spin-off sequel rather than the Mashin Chaser movie we got (which was like mediocre at best since the "robot gains feelings" trope has been done to death but better in other medias).
Aqua dying somehow was the trigger to "harden" Sougo, which is ridiculous. You barely knew the guy. This has always been my problem with Sougo. He gets triggered into caring about people, it's almost like he has no personality of his own. I mean, look back at the Kiva episode (to which I don't think we've ever seen the Kiva Armor, or Blade armor, or even Kabuto or the Agito armor at all). In that episode, instead of using Kivat-bat's voice actor voice Ginga, they could have had Kivat-bat be the one who hands the Kiva Ridewatch to Sougo. But of course, paying Jiro's actor to come back saves them the hardwork of actually doing CGI (to which, I say the cost of is probably higher than just letting someone come in and do the CGI work). Or, Another Kiva could have been Kivat-Bat who got turned into Another Ridewatch instead of the pointless romance plot they have going for Sougo.
You see, you'd expect something like losing a loved one would make Sougo harden. Not another Rider who he kinda had almost no relationship with prior to their meeting dying. Yeah, I enjoyed seeing Aqua back, and seeing him fight Eternal and all that, but Jesus, could these guys be more inept at storytelling?
They also missed out on making Another World where Aqua remained as Poseidon and have them fight each other.
Tsukasa becoming Zi-O was like, okay, I get it, we're going for the double effect of two anniversary show Riders, one acting as the senpai-like figure and the other the kouhei. But if all it took was the Decade Ridewatch to get Tsukasa half his power back to be able to transform, you'd think he'd ask for it back sooner than after getting blasted by Swartz and needed Kaito to reverse his death for him.
Kaito becoming Zi-O II was also completely unnecessary. Just because they both share Rider Summoning powers, doesn't mean it's applicable in any sense to make him shift from one to another from a writing standpoint. This is just, and repeat after me, LAZY WRITING. I don't care if anyone likes this show, it just shows you've never written anything in your life or wrote too much fanfiction to begin with or even read good books or comics/manga.
There is a universal standard for how things work, Joseph Campbell even wrote a whole book on the Monomyth for a hero's journey. It's fine to subvert it and deconstruct it, IF YOU KNEW THE RULES BY HEART. Clearly, Zi-O's writers don't.
Just compare it to Watchmen, a true subversion and deconstruction of the Superhero genre, or Hunter x Hunter, a deconstruction of the Shounen genre, and compare that to stuff like Star Wars The Last Jedi and Sword Art Online (both are trash).
These kinds of stories require no hard work. I could crank out something like this in a few weeks to months. Just because you put effort into doesn't mean it's hard work. And hard work doesn't mean it's good work either. I worked hard scrubbing toilets once as a janitor, and even I wouldn't call that good work.
