I have to say, it's enjoyable despite it all. This "adaption" barely have anything to do with the actual webtoon, so when watching it you will be to keep an open mind and treat it as something else and not Lookism. Otherwise, you have have a very hard time. Don't think of it as an adaption but as a show inspired by it.
The overall story is good in my opinion though I wouldn't say the best. It did get me to anticipate the next episode. The character development is satisfying. At first, I was very angry with how they portrayed Zack but my anger calmed down later on. The one doing Zoe (at least I assumed) though, ehh... I wouldn't say the same. There' some changes but not satisfying. Rewatch? I might but that like crazy like I did with ALing. But this is all my opinion, not trying to offend anyone.
