I enjoyed the movie, especially the chaotic bickering of the entire cast but mainly IU and Seo-Joon's characters. My only problem with this movie is the way they wrapped up some of the characters' story. I liked In-sun's story so I was kind of anticipating how will they wrap it up but it left me confused at the end; Was his encounter with the girl from the Japan team just an imagination or something? That's how I see it given that he also saw her image on that girl who bought a magazine from him at the very end of the movie. Also, I feel like some of the characters backstory was lacking (the gangster guy and the gay character) compared to the others (the IMF uncle/ the construction worker uncle). All in all I still consider this film worth watching, there are a lot of moments that will make you emotional and ecstatic.
