The new anime has the vibe of kimetsu no yaiba and tokyo ghoul. Because it is just the first episode, can't gauge if it is good or not...
Do the three episode rule If you find it boring after three drop it If yu still like it then srick with it
The adaptation of the manga source material so far in my opinion is quite good, and the pacing and story development has a bit of "old school shounen vibes". If you like shounen series where the characters and their backstories as well as the overall story are very carefully written and unraveled and presented in a slow, very deliberate and well crafted pace the series might be for you. Some folks don't have the interest or patience to wait so long (which is fine, diff folks watch the anime medium for different reasons). But that is the sort of thing you will be getting into (based on the first 3 eps), I think.
