It really isnt my type of anime and didnt really liked it for a few reasons.
Protagonist: Protagonist is young and is still a child, which doesnt make any sense because he has to save an entire county. A teen would have been alright, but having a kid just isnt serious enough in my opinion.
Animation: Clover works did a good job animating this one and I think they are the reason this anime got so much hype around it. I guess it just shows how good animation doesnt always mean anime is good.
Characters: Tokiyukis gang is full of kids with only one adult who is weird and annoying. Much like the protagonist I just cant take them seriously.
Elusive samurai had such a great potential with its setting, it could have been a solid seinen manga/anime if it didnt take itself so childish.
In the end Elusive samurai had a misfortune of being a stereotypical shounen anime with nothing new to offer. Its clear its just a seasonal hype and nothing else.
Now this review isnt really detailed and I have a reason for that. Im too lazy to write a longer review
