I definitely liked this series,as i am fan of base building,adventure,magic,action,romance,isekai. But their were few issue that concerned me.(1)i know this series name is how a realistic hero rebuilt the kingdom but they made it a little bit realistic way which i didnot like(2)No need to explain unnecessary things thoroughly (3) as this series mentioned this has genre action where is it i was very disappointed in it as it is lack in actions as we are talking about fighting demon lord not only building nation(4) there is magic in this series where is the use of it.this is the major point here how they didn't actually utilise magic for their own benefits and the protagonist,well he is here to save his Kingdom from demon lord not for base building so why didn't he yet gain knowledge about any magic nor he did any training, this way that would be much more fun to watch. This series desperately need actions scene which are atleast the level of wisemans grandchild,if they can do their actions scene like sword art online then it will be even better(5)And here season 2 ended there is only the protagonist expanding his dominion,while the demon lord is there sitting on chair while sipping tea and enjoying the show.they have no concern for what is he upto or how should they defeat demon lord they only are prioritizing building their domain.i am 110% sure that the 7.1 rating would have been 8.0 if the writer and director took it into consideration. Point to be noted: this series need more serious action scenes and i will prefer a little bit more romance.otherwise this series is a must watch.plus points of this series:i liked the animation very much, storyline is pretty good,All the characters are designed beautifully .if they make their new season with a little bit of actions and romance.i am sure this series will grow more.although this is my personal preference i will leave it to you guys that you should watch this or not after reading my review. EXpecting so good things from season 3. Dont disappoints your fans creator.
