It was really good, gave me some goblin vibes. That one person who said it Will have goblin-type ending was right! hehe

OST
It was okay, but i didn't really Pay attention, it wasn't ear catching.

ACTING
Maybe because i watched all dramas IU has been in that i love her so much, but she was wonderful! Her cold-hot, bratty attitude was refreshing and not annoying! Yeo Jin-goo was fine, didn't partculary stand out sadly. He was main lead but was lacking in comparison of Lee do-hyun (past lover). Lee do-hyun and IU had such good chemistry i felt sad he wasn't main lead. Personally i didnt feel anything from him, and it seemed that if he was crying or sad, i'd feel more émotion towards Sanchez than him! Even tho he is main lead!!! Everyone praised him, but personally he was the only one lacking hère. Other actors who played side characters (Mira, P.O, Yoona, Sanchez etc....) were also gréât. They weren't lacking at all, and for side characters They did a fantastical job portraying their own charisma.

PLOT
It was refreshing to see it, a girl being stuck in Life forever, hosting a hôtel for dead. Pretty unique for me, and characters were unique themselves. They all had a part in the story and weren't there just to be there. They had history which is nice! Altho there were a few cliches that i hated, it was a drama where nobody was stupid enough to let a misunderstanding drag on and have a huge impact. I loved how writers didn't pull out a wild card at the end that something magical happenes and everyone is happy! I teared up réal hard at the end, but loved the cameo of someone spécial, it created a perfect opprotunity for a second season which i hope happens. The plot was nicely written with minor plot holes, overall it wasn't the best drama out there, but for a reason its hyped and loved so much....
BUT
The ML was actually very shallow. Now that i reflect on this drama, i dont like him any bit. The actor wasn't boring per say, because that is his character. He has a personality? Where? If you told me that he was a male lead i wouldn't have believed without watching all of it, since he seems too...boring. Was he only there to drive Man Wol plot or was he suppose to have a purpose? Heck Man Wol, who wasn't suppose to be expressive emotion Wise, was more than him. Which is terrible! The only reason i would watch this again would be because IU really performed well.
