The concept is extremely clever, accompanied with great characters that don't shy away from being completely overpowered in all the right ways. The animation is unbelievably fluid, using 3D animation in ways that are subtle and barely noticeable. I really do wish that they would drive home the ideas of "The right way to die" more, but it seems more like it would focus on that idea around the inevitable end of this series.

I am going to use this space to talk about the highlights this show brings.

First off, the characters are pretty well written. The dialogue is intriguing at times and the ideas that come through the table because of the way these characters are written are honestly brilliant, as they are often unique ideas, or ideas that conflict with the overall final idea of "The right way to die".
The designs of the curses and the characters overall are solid too, they serve their purpose to establish a character simply by looking at them, or divert the audiences expectations entirely as the characters act entirely different as to what you'd expect.
Another aspect of the characters I would like to speak on specifically is how incredibly overpowered some of these characters are. Gojo, to be more exact. He is overpowered in every way that counts. Gojo's character felt off in the beginning, as he constantly felt too casual when it came to curses and something as abhorrent as them, but when we finally get to see Gojo fight, his character writing and the way he acts fits right into place with how overpowered he is. Gojo is one of the best characters in this show, and I'm so happy with how he was handled.
The animation is BRILLIANT with some of the most fluid action scenes in an anime I've seen in a long time. Every punch feels like there is weight behind it, and even the strange and taboo fighting that goes on is believable due to how brilliant the animators have made this series. Honestly, this series would not be as good as it is without the talent behind the animation.
The last point I would like to bring up is emotional beats. This show manages to understand and respect it's emotional beats, and doesn't try to make things lighthearted when shit goes south, like other Shonen anime. I honestly respect how Jujutsu Kaisen respects emotional beats.

I am now going to use this space to talk about the lowlights this show brings.

Exposition. This is inevitable with Shonen anime's, I know, but it still makes a large portion of the episodes feel underwhelming and honestly boring, with a lot of the exposition dumps being explained later in a much more interesting and visual way. It's essentially there to fill time, which bugs me quite a bit.
Another thing that bothered me was pacing. At some times the pacing was spot on, but would often be brought to a screeching halt whenever there was an exposition dump, and that brought me right out of the experience.

This series holds an unbelievable amount of potential, and I cannot wait to see where it goes from here.
