I really loved this kdrama and it that held so much potential with its strong cast of experienced actors, captivating plotline, well-produced OSTs, impressive visual effects, and a generous budget. However, despite its many strengths, the drama ultimately falls short due to its disappointing writing.

One of the most significant issues with the show lies in its confusing and convoluted narrative structure. Constantly switching between different timelines, parallel worlds, and flashbacks without providing clear indicators to the audience left me just feeling disoriented and I was just struggling to keep up with the plot. It would have been better if the writer offered more context and hints to help us viewers understand which world or period they are currently witnessing.

Another major disappointment was the dialogues in this kdrama whcih unfortunately suffer from being cringeworthy at times. While this may not be a major deal-breaker, it certainly detracts from the overall viewing experience. More polished and well-crafted dialogues could have definitely enhanced the emotional impact of the story.

Another major letdown in the series is the treatment of the character Lee Lim. The drama built him up to be an almost invincible force, only to have him captured and killed rather abruptly. Literally, he was built as if he was the next Thanos but he lost with just one bullet.

I also hated the inconsistency in the rules of the world established by the writer. They just made many rules and then broke many of them without any proper explanation, for example, they said only living things could move in the rift between worlds but somehow FL's bullet worked. The show would have greatly benefited if they maintained a coherent set of rules throughout the narrative.

Then there was the portrayal of the female lead, played by Kim Geo Eun, which is another point of concern. While she starts off as a strong and independent character as always, her development takes a frustrating turn, and she becomes a damsel in distress, relying on the male lead for support. Seriously she barely cried in the first 3-4 episodes but near the end every scene showed her she was crying, like wtf.

But even with all these flaws there were still some good things such as Woo Do-hwan's acting and the plot. but yeah for me this would have been an easy 10 if they just changed the writer and dialogue writer. And lastly I would say the rewatch value on this is pretty high for me because this just feels like a story that you have to rewatch to completely understand it
