I came into Hotel del Luna with several biases, but I enjoyed it for the most part (except for the ending, which I really found unsatisfying). Usually, the fantasy tag is an automatic skip when I'm looking for prospective dramas, since I think the extra layer of contrivance often sets up ridiculous plotting and a lot of fat a show could trim off. I didn't find this to be the case with Hotel del Luna, overall. I'm also not a fan of frequent flashbacks, which this has, but here it makes sense given the nature of the fantasy and the premise. The way they're interlaid into dreams makes sense and so the majority of the setup in the beginning and middle is pretty artful. More superficially, I think the costuming and set design was a definite aesthetic draw - it reminds me a lot of It's Okay to Not Be Okay in how it's used as a supplemental pleasure to the main drama. The music is also nice throughout. Overall, there's a lot of visual and auditory appeal in this.

(General spoiler) I really like IU, as most going into this probably do. She does a great job, as does the ML; they have strong on-screen chemistry and their characters' dynamic works well. I do wish their romance was more intimate, though; much of their relationship is threaded through teasing banter, on the one hand, and long-term promises and commitments on the other. As the conclusion was coming up, I felt like the reality of the romance (indicated by the former) faded for the sake of the fantasy-driven resolution (the latter). They flirt but their relationship is weirdly desexualized because IU's character is somehow a 1,300 prude when the chips are down and the ML shows even sarcastic interest. Usually, I think shows can verge too far towards fluffy/intimate, but here I felt like the weight of their choices actually called for the sex/marriage institutionalization more than so many lighthearted shows I've seen that pursue that direction. She kisses him like 3 episodes in - or so it seemed - but that's basically the extent of their romantic intimacy besides some nice chaste hugging. Instead, we get extremely heavy romantic statements of commitment at the expense of fluffiness. Though I typically don't find it necessary (or even desirable to include it), I think having sex and more moments of intimacy in this show could've better shaped the drama at the end and added more levity as well (I think of how that would've fit within the pseudo-gossip the hotel workers had between them). In short, I think the desire to be true to the show's fantasy premise overwhelmed the desire to have a satisfying romance (with all the attendant intimacy), which is ultimately why the ending didn't work for me at all.

(Spoiler) Halfway through, my rating probably would've been closer to an 8.5 or a 9, but the ending made me rethink the parts of the show that I enjoyed from the beginning and middle. My central question throughout the run was, "are they going to be able to stay together in the real world?" But as I got to the end, the creators clearly thought more in terms of "what's the right way for IU's character to atone and thus for us to wrap up the fantasy side of things?" As someone who watched primarily for the romance, the ending was very unfulfilling and frankly didn't make sense to me, especially the ML's actions and what he says to the FL about moving on. I think having reincarnation as a facet of this drama was a fundamental mistake, though one the creators relied a lot on for conflict in the middle and end. Rather, I think the drama of losing immortality and reintegrating into society while dealing with lingering grudges would've been more compelling narrative. I don't think fated relationships - something established in this show via reincarnation - have any real stakes or emotional fulfillment (because choice is circumscribed by destiny), so having the resolution based on some nebulous possibility of meeting again in a reincarnated future does nothing for me. Here, they overcome and change in substantial ways only to lose what's most meaningful to them. Ultimately, the fantasy side of this drama, which I didn't mind for most of the run, led to this kind of unfulfilling conclusion (and on a shameless cameo no less). Like the show's creators, in the end, the main characters are more concerned with an imagined future than with the material reality of living and cultivating romance out of tragic circumstances.

(Spoiler) Rather than romantic or cute, I found the ending to be a weird mix of cynicism and idealism emerging out of the religiously-inflected fantasy. IU's character never lived a real life, never got to be someone because her life was conditioned by the cruel machinations of fate and the stain of vengeance. Once she meets someone with whom she can live and be free, she has to say goodbye because a gaggle of mercurial Fate bitches basically say so. In such a case, it's not clear what the ML should do in his regular life afterward. He falls in love with a gorgeous millennium-old demigod who he makes eternal promises to, but after she moves on, he's supposed to just live basically a regular life? His whole existence at that point is conditioned by the knowledge that his deepest happiness is contingent upon dying and meeting someone he won't remember in a reality he can't fathom. That's not the leap of faith that makes a good romance, but a religious deferral and rejection of the joy of living. The structure of the show really made me think the ending was a punishment of the FL (and the ML by extension), rather than the struggle to move on from her grudge (as it's presented). So the problem, to me, wasn't that the ending is sad (which it is), but that the basis for the resolution - reincarnated future hope - is nonsense and unfulfilling.
