This is a good example of how music can carry a show.

Season 1 :

The plot is really good and even has a great cliffhanger. The general atmosphere is very pleasant, and what can I say about the music? Oh my God! You could literally watch this anime just for the music. Kevin Penkin is still quite young in the anime world, so I have no doubt that he will become a legendary composer in a few decades.

However, in terms of character development, Raphtalia and Filo are great. As for Naofumi, I have mixed feelings. The other heroes, as well as some of the other characters, could they be more stupid?

And what about turning your back on your opponent to talk for 20 minutes in the middle of battle? Stop that crap, it's pathetic (I've always wondered what the enemy's point of view must be like in this situation). Some episodes are boring to watch, while others are brilliant. To the point where moments of "daily life" are much better and more exciting to watch than a battle you've been waiting for..

Season 1 : 8/10

Season 2 :

I don't think this season is all bad. In fact, there are some very good things, and the plot is moving forward. Unfortunately, I think the ending of season 1 should have been different.

During the fight between Naofumi and Glass, Naofumi should have ended the fight by hindering Glass, taking his teammates with him, and using his shields to try to reach the rift and then cross over to the other world. We know that he didn't want to kill the other people. That would have been a good way to move the plot forward, and we'd have a whole season in the other world, so much more developed.

But most of all, find an antagonist other than Kyo. Making a character that is inherently bad, that screams and talks badly all the time doesn't make him a good antagonist. In fact, it was unpleasant to watch.

Otherwise, the OST is once again a masterpiece.

Season 2 : 6/10 (Thank the OST for this rating)

Season 3 :

Exactly the same concerns as season 2, there are some very good things.

I enjoyed seeing the development of Naofumi's village. The addition of new characters to the shield hero group. The arrival of the vassal weapons of this world.

But there's still some bad and very bad stuff.

Malty, again and again and again. It's boring, it sucks. Sure, it unlocks the curse on the various heroes. But after a while, the story needs to be renewed a bit. Some battles where lvl 30s have more impact than lvl 70s, it gives importance to secondary characters, but there's a limit. Are we talking about demi-humans? They never grow up. It's explained to us that they grow as they level up, but even after lvl 40, the class change, they don't grow at all.

Honestly, if Malty plays another manipulative role next season. The only solution is for her to get killed while trying to manipulate the kingdom Naofumi wants to go to. But if they are all stupidly manipulated, I couldn't do it, I'm sorry.. Even the music won't be able to save the rating that I'm going to give to this season 4.

Season 3 : 6/10 (Once again, Music keeps the show alive)

Conclusion: The universe in which the story takes place in is incredible. The multiverse, the interactions between the different worlds, the wave system, the hourglass, legendary weapons, vassal weapons. All of these things are brilliant. On the other hand, I have the impression that the author has lost his way and doesn't know what to invent to renew the story. We turn arround with Myne "Bitch". Always the same thing, over and over again.
