Hands down, Hotel Del Luna is one of the best k dramas. I have ever watched. The leads had excellent chemistry and always stood by each other. The plot was well executed. I have only praise for this drama. I love how everything is not explained in too much detail. If everything is set in stone it seems like an info dump to me. So I adored how the writer left some things open ended and give us hints to fit the pieces together ourselves. I'm very intellectual and thought-oriented which made this very engaging for me. The plot was very unique and had well planned and timed flashbacks. I can't say enough about the OSTs. They are the most beautiful things ever. I could listen to the tracks forever. Crime and thrillers were neatly integrated into the already multi-dimensional plot. Don't believe anyone who says that Hotel Del Luna has a sad ending. Like I said, it's for the audience to form their own conclusions. Overall, its the best. The ratings reflect exactly how good this drama actually is. Infact, I could even call this drama underrated for that is how good it is.
