Looks like this series getting unusual hate from teen audience . No doubt it has some out flows but it doesn't mean show is bad or lacking something serious . It offers you a package of emotions with good adventure in ancient japan e.g old dresses , training , samurai style which you expect to be delivered from a show like this . So, watch yourself without believing negative reviews because someone trash is someone gold ( rent a gf fandom exists) . As you know season 2 is comming next year hope so it improve out flows from this season by adding more good part init ( adding traditional music isn't a bad idea )
