The ilustration is pretty good, some CGI but nothing too invasive, it has it's own style. People remember the action scenes the most but the style that it has most of the time is actually very cartoony and it looks good for what it is. Of course, the action scenes are outstanding visually. They are incredibly fluid, the illustration is on point and has no quality drops and in general they just give everything anyone could want.
At least in soundtrack and visuals because the writing is not that great.
The series have some high peaks, but generally is not that different from any series. Cliches everywhere, one-note characters, power-ups. It's shonen, basically, a regular shonen.
It tries to have some different aspects but none of them goes too far. The tragic backstory of the antagonists are barely explored and have very little weight, the power system is one of the simplest there could be, the battles are being beaten until you get inspired and beat them instead.
There are even some things that are outright bad. Zenitsu is a one-note character that even when he takes part on some really good scenes is obnoxious and is screaming most of the time. Inosuke is the same minus the obnoxious part and Tanjiro is pretty bland as a main character. (Although not as much as Nezuko).
Strangely, even with all of this, I still recommend it. Is a good entertainment if you can ignore the writing faults and has enough good things to balance out the bad ones if you are not looking for anything spectacular.
