Kouta wasn't naive so much as idealistic. Or maybe he was, I dunno, I don't quite remember all of Gaim.
Also, Gentarou wasn't a delinquent. He passed his classes.

Concerning your question...Yeah. Since KR features one prime protagonist, they try to keep their titular character from feeling like a pastiche of the previous year's character.
Secondary characters they unabashedly copy-paste, though.

Eh. Shin is generally way more of a straight-man than Shotaro is, despite how hard the latter tries to be. I think Shin also has a stronger conviction of justice, where as Shotaro mainly just cares about the well being of his city.

Some times I think going back to basic is some times need l. I means it might not be hard to do a showa era style show today with gimmicks' included. I mean main hero forced to be cyborg now want to stop said evil organization with new power up to unlock to fight

I would say the next rider can be someone who is afraid of everything and doesn't have guts to stand up for his beliefs... until something changes him and alters his personality that would make him a hero.

I got question regard about Kamen Rider Ghost Summer Movie

Why did Hermit say there's 15 Great Heroes when Summer Movie reveal that there's actually 71 Great Heroes

Gramps lied us all! That's why I shouldn't trust this old fool! Or he just forgot that there's 71 more heroes?

He said you need eyecons of 15 great heroes the get your wish. Presumably, you could have had any mix of any hero from all over the world- (Haruto) Takeru just happened to come across the main 15.

Aside from that, I had the same theory that there's possibly endless Eyecons to be found since there are so many people who would qualify to be worthy of an Eyecon, but then I noticed that 15 is still a very specific number and if there were more than 15 wouldn’t the bad guys just create more until they had 15 instead of hunting down the ones Takeru and company have?

So I think that there's either just 15 needed for the ritual and it just so happens to be that only 15 exist in Japan at the time, or there are indeed only 15 but not because there are only 15 great heroes but because there are only 15 Eyecons which could be filled with a heroic soul. Basically there are 15 blanks at a time and you can summon up to 15 heroes out of thousands until you can’t summon any more. And after a time they reset and the Eyecons become blanks again, kinda like Dragonballs become rocks after you made your wish.

And of course some Eyecons break the rule so they can have their movie items, and so on and so forth. But basically I think the blank-system could be how it works.

That does make sense, but it doesn't explain how they have eyecons for Takeru and Makoto's souls. Unless they work on a separate things.
Also, Haruto would have wished everything back to good by now :p

I guess Gramps made some more for some reason. He probably gave Takeru's dad the blank that would eventually contain his Takeru's souls and he maybe also made the one Makoto uses.

He probably made all the Eyecons now that I think about it. So maybe he did make only 15 to create enough power to go to this wish-fulfilling place or something, but made more when he needed them. Which would explain why the bad guys can't just create more Eyecons, because Gramps and only Gramps has the knowledge and he isn't sharing it with anybody.

Since all Eyecons pop out of Drivers which Gramps also created it isn't to unlikely that it works kinda like that.

And knowing Haruto, I’m pretty sure he would’ve used the wish on Koyomi and left it to Mr. Mayonnaise to actually deal with the problem at hand.

To be fair, bringing back Koyomi would have taken care of his plan . And then we let Beast kill him anyway. :lol
