I thought Takeru was one of the best reds we've had in a while. Not really over played like Sousuke, but with enough subtility to make him likeable to me.
And I thought the samurai stuff was just enough to be cool.
Did you honestly think they were going to do a musket? Everything has to evolve, including samurai. If the samurai code were still in effect today, with all of our modern technology, I could see the samurai being a lot different.
Also the "discs" are the guard of the sword, and give that old-timey praxinoscope feel to them.
I haven't seen the last ep yet (Waiting on subs....Still waiting...), but I've enjoyed it so far. This has been one of those seasons where I've actually liked every single character, and am really on the edge of my seat to see what the last ep will be like.
Anyway, Shinkenger, to me, feels exactly like what it is: a MODERN DAY samurai story.
Fun fact: Shinkenger is named after the art of Shinkendo, or "Way of the Real Sword". Shinkendo also incorporates Toyama Ryu, Gunto Soho, Battojutsu, Battodo, and jokyue.
