I read the original WEBTOON and while I can say this drama does not compare to the original source material especially in regains to the main character (he’s like super bland in the show). Honestly most of the major characters from the WEBTOONs get a major downgrade in terms of quality and depth; however, the opposite is true for the wider supporting cast. They do a great job adding more survivors to flesh out the cast—dog lady was a personal favorite of mine. Not intrusive or spotlight stealing, but a felt presence.
The show is decent for what it is and I had a fun time watching it. If you want a masterpiece go read the WEBTOON, if you want an enjoyable show to binge then watch this.
