We got to see Cha Hyun-su (Song Kang) more screen time than the second season and that's good, because well he's supposed to be the main character.

The pace is fast, you really watch it in one sitting, the scenes were much more well done than the first and second seasons. Obviously people can have criticisms about characters that were removed and included. Well that's normal, they live in an apocalyptic world (something like The Walking Dead), not all the characters manage to survive and they have to introduce new characters.

People also complain that there are unnecessary deaths (well if you are not used to this type of genre it may shock you, but when you are already used to this type of genre you know that this will happen). There's a reason my older brother and I, who enjoy this genre, usually say "don't get attached to anyone, because you'll know they'll die."

About the motives of some characters... well I come from the old school of The Walking Dead, so I have understood that some characters do not have a reason to act or be differently. Human nature is already monstrous, you will find that there are people who really have no reason to act in a monstrous way. Even if you kill yourself analyzing why, you'll never really find the answer in the real world.

About Lee Eun Hyuk, I know many were hoping to see him again. But you have to understand that she presents herself as a counterpart to Cha Hyun-su. Chan Hyun still maintains his human emotions, while Lee Eun Hyuk, after his transformation, has to deal with regaining some of his humanity. Not all transformations are the same, so they can have different nuances. For some reason, his sister tells him that I tried to remember how it felt to be human, so as not to become a total monster.

Pyeon Sang Wook, he doesn't die for no reason. He still kept the human part of him even though he was possessed most of the time. If you see from the first season everyone feared him but deep down, with his hard shell to never suffer again, he was a gentle man. So he preferred to die along with his monster before his humanity was completely lost.

Honestly there will be no fourth season. This is the end, the monsters will have to learn to live with humans and the three main characters deserved to be happy after everything they went through.

I want to say that your opinion is valid if you were disappointed by this last season. But in my opinion, if you have not traveled a long way through this genre, there are many things that you will not like and you will not find meaning in it. But for those of us who already have a long history in this genre, you will really enjoy it and understand many things and some things, characters that die or actions of some characters, do not seem incongruous.

For my part, I enjoyed it a lot, from the story, the ending, the acting, the soundtrack and the cinematography.

Spoilers about the original work, they actually tied up loose ends about Hyuk, that it was unknown if he would become an unfeeling monster or not. Here they leave you to hope that Hyuk is trying to keep the human part of him from disappearing.

At the end of it all, because they are still alive. Well, they are still alive for those they lost along the way and that their deaths are not in vain.

Many people also die in weebtoon. So I wasn't really surprised about that. Furthermore, I reiterate, that I am used to seeing many deaths because I consume this genre.

I think you have been disappointed, I can tell you something: investigate more about this genre and you will realize that the story followed the pattern of many series of this genre and secondly, never get attached to anyone! Otherwise you will suffer when your favorite character dies.
