Okay, so, i'm fairly new to Tokusatsu in general, getting into it when I got sick of hearing about Godzilla, but still wanting a fix of cheesy Japanese suitmation, and i'm already decently familiar with Ultraman and Super Sentai, but I know almost nothing about Kamen Rider. So, what would be a good series to introduce somebody to Kamen Rider? Like, which series best explains what exactly a rider is? I've done some research, and I guess a lot of people point to Kabuto as being one of the best Rider series, but I read a plot synopsis and it seemed like something that would be more rewarding to somebody who is already familiar with Kamen Rider in general. I've also seen a lot of "just pick one that looks cool and you want to see in action" type answers, which makes me want to watch Gaim (because everything in it looks awesome) but it also sort of sounds like something that won't explain things too well.

Would it be good to start with an early series? I love old Godzilla movies, and enjoyed what I could find of Himitsu Sentai Goranger. Are there even subs for those? I know Sentai doesn't have a lot of subs for the early stuff, so i'm not sure if it's the same for Rider. Also, sorry if there have been 100 other topics like this, but I can't find any that ask this specific question lol
