Yeah, my biggest criticism with 80s Sentai is that the characters are barely ever developed. There are often times when they never really tell us why the rangers were chosen to be rangers like in Dynaman and Changeman. Okay cool, they have been given powers and were chosen, but why? What is so great about these specific individuals thay they were the ones chosen to save the world?

Why is the pink ranger in Dynaman afraid of cats? They show that she is scared of them, but they never tell us why. How any people did Biorobo actually scan? They only showed us five people being scanned, but since the second yellow exists, there were more, right? Did Biorobo just scan hundreds of people with the particles? Or did he just decide to scan a sixth person because reasons?

Come to think of it, this is probably another reason why Jetman is so loved. People on here might not understand it, especially the love for Guy, but coming off the 80s Sentai with generic one dimensional good guys, a morally gray character like Guy was revolutionary.
