I'm a relatively new fan of the franchise, but for me, the appeal of Kamen Rider is that, at its heart, it's about a guy who jump-kicks monsters so hard that they explode. That is basically my ideal form of entertainment, just evil monsters all bursting into flames because of karate. And apparently, someone over at Toei agrees with me.
That, I assume, is why they decided to promote the upcoming movie, Heisei Riders vs. Shōwa Riders: Kamen Rider Taisen feat. Super Sentai, by putting together a highlight reel of every Shōwa era Rider performing his finishing move on a villain, which usually results in the bad guys exploding, being thrown off a cliff, or sometimes being thrown off a cliff and then exploding. Be warned, though: Some dude is definitely going to have his eyes ripped out and his head punched off, in what is basically an action show for tiny children. It is fantastic.
