Me after seeing Kamen Rider Die will also review Fuuto P.I.: *gets out bowl and popcorn*

Yeah, while doing something new at the time such as two individuals being one rider, I agree that this show definitely is a nice starting point for newcomers, like GrandComplete pointed out, to get introduced to the core aspects of Kamen Rider from the recent batch of shows. Of course, if said newcomers then are interested in Showa stuff I'd suggest OG Kamen Rider, Kamen Rider Black, and Shin Kamen Rider. And by Shin Kamen Rider I mean the recent Anno film, not the 1992 body horror rider.
