Incoherent, dull and bland like unseasoned chicken. It really feels like they strung a few different scenes together - there's hardly any plot and characterisation, if any at all. I didn't find the acting bad, but in the end it didn't amount to anything, since the film only scratches the surface of the characters' thoughts and motives. I doubt anyone who hasn't read the webtoon and/or watched the drama would make any sense of what they were watching and wouldn't drop it after half an hour of random images. As for the music, apart from a song towards the end, the rest was rather unmemorable.
