This season is better than season two by far. There were no randomly new characters showing up, we got some answers, and we got characters meeting back up or banding together in different forms.

However, this season (and season 2 too) is severely lacking in depth, development, and plot.
This season, especially the last 2-3 episodes, was rushed immensely. There is no time for our characters to actually interact in a way that feels genuine - we're literally given a minute to just be on board with Cha Hyun-su, Lee Eun-hyeok, and Lee Eun-Yu finally meeting again, Hyun-Su and Eun-Hyeok fighting for a minute, and then suddenly accepting to go somewhere together! We deserved a whole episode of this just by itself! I was so hyped to see the emotions and the explanations for them all meeting again, but it's literally done in about 3 minutes in the show and the show expects us to just accept it and move on because they split up again pretty quickly too! This show absolutely wasted and ruined the moment it could've been -, also there is no time taken to explain or deepen the lore or answer questions, there is no time spent on building up to some of the big moments of this season (Yi-kyung, final baddie fight, remeeting with a character from season one, the actual ending!).

This show needs at least 16 more one long episodes so our characters, the world, the story, and the lore actually has enough time to breathe on screen, to develop in a realistic manner, and to actually give us a satisfactory story.

The best part of this show is the acting! I cannot flaw one single actor in this. All of them did an amazing job with their scenes, with each other, and their parts. It's just such a shame that the story and the script was not enough to really let them show everything they have.
