[Switchblade]

Full disclosure, I've only seen the film once. Not because of the creative staff, though, just because it's a lot longer than a standard episode and I don't always have that much time to set aside. I remember liking it a lot, though. Like all the other Heisei movies so far, this one isn't canon to the series and it has some noticeable differences, especially in where the final form comes in. It's relatively close, though - no dystopian parallel universe here.

The plot is... well, it's The Seven Samurai with Kamen Riders. There's no way to really pretend otherwise, it's even in the title. It still works, though. It's a good basic story and it plays out really nicely to throw the Hibiki cast and some new guys into it. Add in some silly costumes (oh, Touki...) and a traitor and you've got yourself a really fun film.
