- Awesome Music: 11 Rider Dai-senka. A love letter to all things Rider (at the time) lasting over 8 minutes. By Ichiro Mizuki.
- The opening theme. Takayuki Miyauchi's voice is powerful.
- Contested Sequel: Due to the tone shift, as well as the fact that, for many, Kotaro's story had been told in the previous series, opinions on this one aren't as favorable as those for Black. While it's not outright hated (especially nowadays, considering that there have been series that are seen as worse), opinions on this one are mixed, to say the least.
- Epileptic Trees: Thanks to Emperor Crisis having the same voice actor as The Great Leader of Shocker, as well as the fact that he's a giant floating head and that he's mentioned personally fighting the original 10 riders at some point, some fans suspect that Crisis is actually another incarnation of the Great Leadernote .
- Interestingly, if this theory was true, this would make Kotaro in his incarnation from the previous series the only Showa-era TV Rider not to have fought an organization led by the Great Leader, either directly or indirectlynote .
- Growing the Beard: The series begins with a much lighter and goofier tone than its predecessor (Kamen Rider BLACK was probably the darkest instalment of the franchise in the 20th century)—jarringly so. The arc beginning in episode 14, however, features more tense, serious storytelling throughout, peaking in episode 15, with Kotaro achieving his new Super Mode while screaming in rage with a dead child cradled in his arms. The series doesn't forget its comedic side after the arc concludes, but it does learn to balance comedy and drama better.
- Inferred Holocaust: Big time. When RX destroys Emperor Crisis in the final episode, the Demon World is destroyed as well.. even though earlier episodes showed that yes, there are good people in the Demon World fighting against Crisis. Oops.
- Never Live It Down: Even though Shadow Moon eventually did a HeelFace Turn here, he's usually remembered as a "Kickass Kamen Rider villain", thus he usually gets villain roles in other works featuring Black and RX.
- Retroactive Recognition:
- Special Effects Failure: The Big Bad is Emperor Crisis, a giant demon head. The puppet is pretty impressive...except for shots where you can clearly see the operator's legs behind it.
- Values Dissonance: Episode 14 is going to make public viewings a little awkward, with naked Hitomi (who's like six) and her dad in the bath.
- Vindicated by History: While not to the extent of Kamen Rider Amazon, it's been viewed more favorably over the years - like Amazon, it plays a key role in the plot of Decade. The fact that it's American adaptation is seen as worse doesn't hurt it either.
- What an Idiot!: see here.
