We could have a sequel to Kamen rider Black Rx ?

Probably not. Even if we do get something after the show it would be probably a movie special like Kamen Rider 1. Personally BLACK RX being the end of it all is fine by me.

I haven't seen Fourze yet but judging the trailers for it on YouTube it definitely looks, "Kiddie".

..I'll still watch it though. It's still Kamen Rider

You'd be surprised, Fourze has subtly dark moments imo

It does have some dark moments, but it still very upbeat. The show came out during the 2011 Earthquake and Toei wanted to do a more silly show to cheer up kids & people in general. So I respect them for doing that.

Fourze was made intentionally more lighthearted and happy to help kids who were traumatized by the Fukushima earthquake. It's not that silly, though, compared to some of the stuff we got in Drive and Ghost, both of which leaned really hard into slapstick comedy. I've always felt that those two shows got a little goofier as a backlash against how dark Gaim got.

donæt get me wrong, I enjoyed Fourze, exept when the "subtle" frendship theme got a bit too powerfull, like during the final battle with Sagitarius

and now I'm looking forward to that even more.

I started watching V3 the past couple weeks (as well as Faiz, I bounce back and forth between Showa and Heisei).

I was really surprised that people were getting stabbed and stabbed in the face, the guy with the buzzsaw arm totally lopped someone's head off. I was watching it on my phone in the waiting room of a Doctors office and burst out laughing when that happened. Just totally wasn't expecting to see a rolling head in a Kamen Rider episode.

....I like this series so much. Even Ryuki which I wasn't crazy about I still really enjoyed in a lot of ways. Kamen Rider is just a lot of fun.

It was never subtle to begin with and that's what made the final battle work.

Er... He kinda used quotation marks for a reason
