I'd argue that even pre Den-O series use the two episode format as well. Kuuga, Agito, and Blade all take two episodes to get through the monster of the week, ot moght be less pronounced since those series don't have victims of the week either.

Now I didn't finish it but I from what I watched, the two episode format really hurt Wizard. The series had to spend 8 episodes showing off each of the 4 styles which is fine, other series have done that too. But then I think immediately after that they have to spend another 8 episodes for each Dragon Form of the styles. All this really did in my eyes was waste about a third of the shows episodes of an already slow season

Probably too early to judge, but I definitely feel that Zero-One's been hurt most badly by the 2-episode format -- the concept for the tournament arc was fine, and I agree with the assertion that for the argument you're setting up and with your target demographic being kids, you need to show off a wide variety of industries where AI could be useful. But making each and every one a 2-parter just meant it was dragged out far more than necessary and made it feel even more formulaic than it already was.

Do you think it’s possibly for the next Kamen Rider show to be more uplifting after Zero-One due to Coronavirus pandemic?

I remember the reason why Fourze is about friendship because Toei wanting Fourze to be uplifting after 2011 Earthquake and the production team wanted to make a hero to bring the smiles back to people.

I not sure if they are doing the next Kamen Rider show once they done with Zero-One after Toei studios got shut down due to Rio Komiya (Kiramai Red’s actor) get diagnosed with COVID-19 but fortunately, Rio Komiya is making a recovery.

That wouldn't surprise me.

Toei does have a track record of making series more uplifting and light hearted after a major tragedy.

The kamen rider today are not anymore metal riders.

Thing is with the whole Covid-19 situation, I wonder if it'll get worse and cause the show to be delayed, and somehow Kamen Rider eventually goes back to premiering in January.

I wouldn't be surprised by a delay. Considering the lead for Kirameiger has contracted it and Toei studios are on lock down.
It does make me wonder how far in advance an episode is filmed, now, though.

Get ready for the next rider to be about doctors again.

To be fair, there's already a staggering amount of series that are about random jackoffs suddenly attaining great power :lol
