As someone who is familiar with the Douluo Dalu series, this story doesn't feel quite refreshing or original. Despite that, it's highly enjoyable, hence I finished it in a couple of hours.
The story is like something I have seen before, which is not necessarily a bad thing, as long as it is done right. So far, the story is good, but not outstanding. There are things I personally would like to see go in a different direction, but for now these are OK.
This series art isn't your typical 2D anime, instead it's more 3Dish. I personally appreciate the 3D animation and art style.
The way this series looks, reminds me of a PS3 game or perhaps a Final Fantasy game. It isn't thát pretty, but very well done.
Unlike many other shows that I have watched, where I barely noticed the music, there were some sound effects in this show that I actually noticed. The music and other sound effects are more present, which adds to the show.
The characters are not very outstanding in comparison to other similar shows. Yet I feel like they're still written pretty well. The protagonist is this cocky, weak lad who develops very well. I can't go in further detail about character development due to spoilers. The rest of the characters are not per se developing, yet you come to learn more about them, which is also fun and intriguing.
Pretty much sums up the above combined.
