To get this out of the way, I know that many viewers love this series, and that is great! I don't want my review to hate on this series, but I do want to present a different opinion.
The first few episodes are great! They are visually appealing, have an exciting tone with compelling characters, and the plot progresses at a perfect speed. I was excited and eager to see its potential. However, as the show progresses, everything gets muddy, repetitive, and pointless.

THE BAD: Without spoiling anything, the plot ends up going in boring, unnecessary directions. The main characters had so much potential and what could have been more active, strong roles ended up becoming pitiful puppets or just plain pointless. There were also so many relationships(romantic and platonic) that could have gone in different directions that would make sense and be satisfactional, but these too fell short. Additionally, the once interesting fighting and massacre scenes became tragically repetitive in the latter half of the series and felt like cheap tactics to create some sort of tension. The main character's focus is also changed later on to different people and flip-flops, as well as the main plot. These changes only furthered my confusion and frustration. As for the setting, I quickly got tired of seeing the interior of the hotel.

THE GOOD: The soundtrack was befitting, especially "Bumps in the Night" (a real bop!). The actors were cast perfectly and I enjoyed the costume design and set design at certain parts. The plot (at least at the start) is very unique and interesting.

OVERALL: All of my review is subjective, but I personally did not enjoy this series. There was a lot of potential with such a unique plot and wonderful cast, but it became frustrating instead. I wish I would have stopped watching maybe around the 3rd episode.
