This movie is just amazing!! Song joong ki and park bo young's acting is just superb!! Very heart touching and emotional movie and the ending especially is very sad!! Kim suni shouldn't have left him just like that without even saying a goodbye!! They should have at least shown cheol so getting back into his pack again, living with someone and not alone since in the movie the professor said that the wolves are social predators who live in packs. At least he wouldn't have ended all alone all his life!! Just wish they would have given a happy or just a more proper ending. But I feel good that suni told him that you no longer have to wait. He can atleast move on in life!! The movie is awesome but only one thing that doesn't make sense is that even after 47 years cheol so is looking exactly the same! No difference! They could have shown him a little bit mature. It would have been more realistic since 47 years and no change in appearance even though he's a werewolf but still a animal. He can have a longer life span would slow changes in the appearances and age!! Overall this movie is a must watch for Korean hallyu fans!!! Just make sure you have tissues with you while watching it! 😄
