Tensei Shitara Dainana Ouji Datta Node, Kimama ni Majutsu wo Kiwamemasu

The animation is great.

It's smooth and doesn't cut corners like some others do. (i didn't notice this fighting smearing).

The fights are clear and well-animated, and the style is cool, kind of like "Spy x Family." There's at least one fight in every episode.

The sound design is solid.

The main character is easy to root for. He still got a grown-up side and doesn't get fooled easily, but he's still a kid and is there by adventorous and curious.

The gore is well done - it's the best I've seen in an isekai, except for "Drifters." It's not overused, but it's impactful when it is.

The magic system is interesting and looks like it'll get more complex (is spell combination based).

It's different from "Tensura," which is more about the use of "skills".

The main character isn't surrounded by a harem; people just find him cute.

There is maybe one potential love interest.

The show isn't trying too hard to be dark or edgy which is something you see often in some other isekais.
