as someone who read the Manhwa the anime where good and decent but there was a problem, I couldn't really feel the fear and the hyper i felt when i first read the Manhwa,even when I read it the second time it still had the hype but i didn't feel it in the anime. it seems it missing a big part, but other then that i feel the anime captured the anime, from the voice actors that i see completely fitting to the animation and much more.
