If I may put in my two cents worth on the thread, I've only seen Kuuga, Agito and right now I'm watching Ryuki, Kuuga has a very good story. Its fun to marathon watch that series. Though from reading this thread those three are more on the darker side of story telling I guess.

Someone help me. Was it Kuuga that was supossed to be the last season of Kamen Rider, so they did whatever and ended up making awesome?

What do you mean? Didn't Kuuga restart the franchise?

Yeah. I heard on one of Vange1us's V-Builds(which is totally a reliable source of information...) that Kuuga wasn't meant to bring the series back. It was just a last thing with nearly no budget but complete freedom with the show staff(though I have to ask, if this was supposed to be the last series, why would they make it when the last Kamen Rider show was more than 10 years ago?).

No. No, not even slightly. You're thinking of Stronger.
