Look, I'm not going to tell you that this is best show to ever exist. It's trash, but in the best possible way. Like a giant greasy hamburger. The characters are thin, the MC OP, and the plot is just making shit up as it goes along. If I really had to gripe about anything, genuinely, it's the CG and effects. The backgrounds are okay at best. The characters are regular anime style, not the half cg bs you see some other studios do, but the dragons are probably the worst thing I've ever seen; and I've watched the Berserk 2016. Some of the effects are...They feel really sketchy.
Ultimately, I'd say if you like a little trash in your anime, go for it. Watch it. While the characters are serious, the show does not take itself seriously. There is literally a love beam. 8/10 will continue watching.
