Revice's constant string of changes and rewrites completely destroyed the show.

In fact, it seems to me that the rider is quite good at finding a separate task for each hero. That is, while the main character is fighting the main villain, the rest either deal with the extras or cheer him up without getting into battle.

Since they remembered about Revice, then his main trouble is the sobbing beaten by Daiji. That's exactly what pops into my head when I think about this show. And I understand that this is most likely an illusion, but according to my feelings of his suffering, at least half of the series was shadowed.

I guess to clarify my point from earlier, I do actually like the crossover stuff, in fact I think the crossover movies can be a lot of fun. I just don’t want it referenced or being important in the main show in any way, shape, or form. I also don’t want different Riders from other shows appearing in the current one (unless of course it’s the entire point like with Decade & Zi-O, then it’s fine). I like this stuff as a side thing but KEEP it a side thing.

Also regarding Black Sun, I dug it at first but the ending (more specifically the very very end) was so wack it soured the whole thing for me.

I'm not the biggest fan of specials that tie in with the series as it's airing; it's a lot to keep track of and while sometimes it's nice to get additional side content it also tends to be more on the side of "essential story content they couldn't write into the main show."

I often feel the same way. I'd prefer fun, but unnecessary, side-stories as opposed to "you better watch this if you want to know what the plot is". When you watch a show live you can follow it decently by watching everything as they get released. but if you are watching after the show has aired the continuity becomes a nightmare to try and figure out without reading spoilers. On the other hand if you watch a show after it comes out you can actually watch the movies, which are also often plot relevant! Damned if you do and damned if you don't situation.

Continuing this theme, have you noticed that there are characters on the show whose name is only in the credits or is said once, by the way? This was clearly before, but in Geats it is especially striking.

Blade's ending is overrated
There were multiple ways it could have been solved without turning Kenzaki into a Joker

I agree, but this is what Kenzaki himself wanted. He never forgave himself for the death of his family (in which, of course, he was not guilty, but he felt guilty) and subconsciously wanted to punish himself, while saving someone. Preferably someone close. Actually, therefore, for all the fanfiction of the decision from Zi-O, I like it, because it means that Kenzaki has healed from his injury and is ready for a full life.
But in general, I like the ending of OOO (the show, not the anniversary movie) much better, because there, Agee's kindness elicited a response from Ankh. While the relationship between Kenzaki and Hajime remains one-sided, except that there are fewer fights.

The Grongi language isn't huge spoiler, it's just normal villain speak.
