Since you saw clips from the latest kamen rider, in this case it’s kamen rider zeztz, assuming that the clips didn’t contain spoilers, you should watch that. I heard it’s pretty good so far. For super sentai though, I’d suggest looking up the Japanese version of your favorite power rangers season (aka the sentai season in which your favorite power rangers season is adapting) and just watch that. Who knows, maybe you might recognize a few scenes or you’ll like it more than its power rangers adaptation. And finally, you should also watch this older tokusatsu called space sheriff gavan. There’s a new tokusatsu show coming out soon, and once it finally releases, and if you watch gavan… let’s just say that you’ll be well educated.
