This action drama is set on a futuristic Earth where oxygen has become a scarce resource. A team of deliverymen ensures its distribution to a population organized under a strict social order with high opportunity disparities.

Despite its short length (only 6 episodes of about 45 minutes), this series manages to set up very quickly and properly the stakes, the universe and the various characters. The story ramps up in an exciting way across the episodes: it is packed with action and still leave some room for a deeper thematic, resonating with the preoccupations and actuality of our current times.

The characters made sensible choices and are intelligent, the writing is solid and make sense overall. I would just have appreciated for the antagonist to have more fleshed out motivations and aspirations. I loved the mentoring relationship that develops between two of the characters. This TV show is proof that when done well, the common trope of the apprentice being taught all the ropes and progressing (almost levelling-up in a way) remains a really interesting and compelling storyline to follow.

I was amazed by the performance of Kim Woo Bin: as expected he did a great job. He has such as strong physicality and presence which I find captivating: it is always a real treat to see him on screen. Kang Yoo Seok also really impressed me, I was totally invested in his character and I will be digging into his filmography as he was such a good discovery. Overall, the ensemble cast is really strong and work excessively well together.

The production value was pretty high. They managed to create a quite realistic and frightening dystopian futuristic world. All the details were on point regarding the decors, costumes and accessories. For example, there are several kind of breathing masks (and not just one type used by everyone which would make less sense), there are also a big variety of technologies, machines and digital tools featured across the course of the story. All these elements brought together made the series looks really believable. The soundtrack is mainly atmospheric, providing suitable thrilling or dark vibes. I liked a lot the transitions between some scenes and episodes with the picture shifting to a drawing piece: it was super eye-catching.

I would recommend this to people looking for an ultra binge-able action drama set up in a well-conceived dystopian futuristic universe. If you like movie such as "Dune (Part1)" or even to a lesser extent TV shows such as "The 100" or "The Mandalorian", this will be right up your alley!
