[Switchblade]

I think W has probably my second favorite* storytelling engine of all the Kamen Rider shows. The detective angle is always a good reason to pull the characters into the Monster/Victim of the Fortnight plot and does so in a way that sets up some kind of mystery at the heart of that plot. There are definitely shows that used the same two-part story structure that could be much clunkier about finding a reason for the Rider to be a part of the story.

So in regards to Makura and Jinno, we're seeing another instance of the show really embracing the tropes of the hard-boiled detective genre that inspired it. We have the cop who considers the detective to be an unwanted presence and the cop who respects the detective and relies on their ability to look into crimes without the restrictions of conventional law enforcement. We're just missing the corrupt cop who's in league with the criminals (for now). I really like how W both uses classic detective tropes (so many femme fatales) but is also willing to put its own spin on things (Akiko is aggressively unwilling to be a classic secretary).

*The #1, of course, is Kotaro Minami hearing random snippets of a conversation and correctly assuming that it's tied to a Gorgom plot.
