It's something that's a little weird after seeing so many Rider shows with ongoing story arcs, but I can get used to it.

Well that sounds amazing. No matter how seriously they took themselves, it seems like Showa shows were never ones to dial back the insanity. Which I like a lot.

It is weird. I watched Black right after W and while watching 555 and it was definitely weird going from shows with a story continued in every episode to a show with an episodic feel. Takes some time to get use to it but once you are, you can really enjoy it even more.

Decade 23. Wow it's like Fourteen stepped outside of a GARO episode. Shame he sucked.

Kaitou focus...yay? DiEnd has been almost as pointless a secondary Rider as Beast was (until those last ten episodes) so I'd rather have gotten an episode focusing on Tsukasa's backstory rather than Kaitou's tale of monster Roaches, Missing Ace Riders and a massive bunch of WHY THE FUCK NOT (not used that in a very long have I?).

I agree with you on DiEnd, but I think his backstory is at least somewhat interesting...as for why there's Missing Ace Riders?

I think you said it best:

I'm pretty sure that Fourteen was in fact a re-use of the final monster from Missing Ace. Fits with the theme of the world.

While I'm not particularly fond of Diend, I like that he's a rival/antagonistic secondary Rider who becomes more or less a good guy without having a big friendship epiphany and immedeatly becoming besties with the rest of the main cast (like Meteor did,for example).

Well, Gaim x Wizard is out raw on Youtube now...

This is my problem though, what you've described is a premise of a great character and we never get any more than that in the actual show. Or at least we haven't so far.

Well Kamen Rider X actually has a long connected storyline towards the end of the series. It's one of the few times in the Showa Era.

Yep. Stronger had one near the end, too, with all the Delza Army generals and their internal power struggles.

Decade 24. Oh man that monster DiEnd looks sweet.

Ironically Decade tributes Shinkenger better than Gokaiger did. From Genta's oddly fat suit actor to Suzuka Morita I forgot about the wonders of Shinkenger. Oh how I missed the utter boredom.

Tsukasa is a really odd character, especially so for a protagonist. His heart is in the right place, and when it comes to his friends especially he really does appear to care a lot but he's such a total buffoon but not really in an endearing way as he's also a bit of a dick.
