Sengoku Musou opens with what can best be described is a flaming pile of horse shit. It is, perhaps, the best example of how not to open an anime (or start a visual story of any kind) that I have ever seen.
No, I’m not being hyperbolic. Go ahead and watch the opening and tell me that you understood who anyone was or why a viewer would care about any of it with so little context. Jerkily animating gaudy samurai drifting in and out of clouds and popping into focus only to show us moments of dialogue we have no context for is *&$%ing idiotic.
You may like S&M if you like dozens of long historical Japanese names vomited at you by gaudy, overly ornate and, frankly stupid-looking characters. I presume it’s marginally based in Japanese history, though I’m not familiar with anyone in this show and it’s so profoundly ugly that I don’t care and I would rather eat dog $#!†t sushi for lunch than watch any more of it.
When we talk about info dumping and expositional over load, we’re usually criticizing a show for attaining 50% of the motor-mouthing presented by Sengoku. It’s truly numbing.
You probably wont find anything interesting about S&M because any value it may have (eventually interesting combat, sexy lady samurai in sexy lady samurai armor) is buried under an uninteresting, cliche period drama.
If I knew more about the source material, I would claim this was actually parody.
My immediately, unwavering verdict is: Skip it.
If you must watching it, drink heavily and turn off your brain. The character design is bad. The story is incoherent and slow. The characters are archetypical cliches. It’s a mess and if the visual presentation was any worse, I’d give it a 3 or lower.
