The first episode captivated me. It was beautiful and I definitely enjoyed it. But as the episodes went on, I became less invested in the story lines of the guests and more impatient to see man wol and chan sung's story, man wol's past.
What I liked about the show:
1) the acting. I'm a huge IU fan and I watched this show because of her and she absolutely convinced me of her character as the immortal man wol. Despite her being so young, she conveyed an ageless wisdom with her eyes.
I have not seen anything with yeo jin goo but I was blown away by his acting skills. He and IU had definite chemistry.
2) the ost. I might not listen to them as separate songs (done for me and another day being exceptions) but they definitely complemented the show.
3) cinematography was beautiful. It was charming.
4) the way the makers handled the plotline of the vengeful ghost of the young woman whose video was made viral. That was in my opinion the most interesting episode
5) loved the way ms.choi's arc was completed. Her arc touched me the most and her conclusion was beautiful.

What I didn't like:
1) the amount of time each guest would be given per episode. There needs to be a balance because we need the already present characters to develop too.
2) the way the arc of man wol's first love was handled. I think its because the plot of the show is a little similar to goblin but I couldn't help compare and appreciate how goblin handled the whole grim reaper and Kim shin confrontation better. Considering how man won spent 1300 years resenting this man who she believed to have betrayed her, the moment they finally met was so lackluster. It was like she felt nothing. No emotions at all. Just because she had found love with chan seung did not mean she could not have had one decent conversation with ko chung myung. Same goes with the reincarnation of yeon yu. I liked the way goblin handled the subject. How despite sunny not knowing her brother in her current life, he still managed to get to her. I would have liked to the main characters from that time 1300 years ago to have alteast one moment where they were togetger. The fact that there was barely any interaction made the 1300 years of wait seem like a childish thing whereas we know it wasn't. It was 1300 years of pain, anger, resentment, hate and self loathing. Not to mention that ko chung myung stayed with her as her first guest. But not even that is acknowledged by man wol. It was all kinda anti climatic. Given the build up. Also it kills me that man wol will never know that it was ko chun myung who brought back chan sung safely from the tunnel. I'm not saying that what ko chun myung did 1300 years ago was right. There were many ways he could have avoided the situation. But given that he more than paid for what he did, I expect more from when the two would finally face each other. Both having lived 1300 years with the past in their hearts.
3) the episode in which man wol gives the hair pin to vengeful ghost out for for chan sung. I get it. She thought he was the reincarnation of that man she had hated for 1300 years. But I kept thinking that she would not go through with it. That she'd come and save chan sung. But she didn't and was prepared to vanish. I think that was the only time I genuinely disliked man wol. And because that particular moment is never addressed again, I could never like man wol as much as did before. She would have gone through with it. She would have killed chan sung through that ghost and taken the coward's way out by vanishing. The fact that she couldn't stab chan sung when he offered her the dagger meant nothing to me as a viewer because man wol had already stated that the reason she gave the ghost the pin was because she could not kill chan sung herself. So why did her letting go of the dagger mean she was overcoming her hate when she really wasn't? I wish that this particular plot line had been handled better. Like man wol giving the ghost that pin so that it would finally come out into the open, confident in its new found power, while she secretly protected chan sung. They could have shown that she didn't tell chan sung to make it seem like chan sung had truly been abandoned and so they chan sung could go look for the ghost and be more believable about how he had been abandoned by man wol. They could have even shown man wol having a change of heart at the very last minute and showing that it didn't matter to her who chan sung was in his previous life. By showing that she gave the pin to the ghost and by not doing anything she showed that nothing had changed for her. I'm bringing goblin back into this because we saw the way Kim shin came to terms with grim reaper being the king's reincarnation and the way it was handled was beautiful. In hotel del luna, this was poorly handled in my opinion.

That being said, it was a good show with solid performances, good chemistry between the leads and I honestly do get the hype. And atleast this show did not shy away from showing some truly malicious ghosts (unlike Master's sun which made it seem like all ghosts were nice and not dangerous)

My absolute favourite moments would be when man wol reaches the tunnel where chan sung had mistakenly gone and runs to him when she seems him. That moment when man wol's cold exterior came crashing down and she felt true desperation will always stay in my mind. And secondly when man wol fights with ko chun myung and he talks to her about he had wanted to see her dressed as his bride, as she waited for him. How he would then reach out and touch her cheek. For some reason that scene hit me hard. I was all choked up because here she was, the girl he wanted to marry, dressed as the bride but holding a sword to his neck. That moment was strong and kudos to the actors for making it so. Third moment was when man wol returned after seeing off ko chun Myung and chan sung ran to her and just held her, not letting go for a second. the way he enveloped her in his arms and stood there, shaking, was a brilliant bit of acting.

As for the end, since I love happy endings, im going to stick with my interpretation: that chan sung and man wol met each other after they were reincarnated and they remembered one another (hence chan sung reading the book existence and time). I'd like to think that this particular blessing of remembering one another was a favour granted by the magos to the staff of hotel del luna for all they did to help the ghost guests. its also possible that chan sung was not reincarnated and man wol came in his current life time (which is possible since the show told us that time flowed differently beyond the bridge)since we don't see yuna in the park where everyone else is which is odd because everyone else was there. so I stick to happy ending version cuz I love happy endings
