I thought it was an interesting concept to have a rags to riches style in a unique way as this. It seemed to have a good build up and structure with some possible hurdles made clear to the audience to build that suspence which it did very well. I liked the style of the film and thought it was well shot with room to improve.
However once it got about an hour into it, the plot completely fell apart. The fact that no one worked out what they were doing was unbelievable and after all that could've happened to the couple, the only thing that really affected them in the end was guilt. Not the police, not Mr Mun who had a very clear motive, not the father who despised his son-in-law, none of this mattered in the end. The kidnapping of the girl was some subplot that barely involved the couple and was merely a red herring for the audience, it got too much airtime to be that insignificant.
I thought the humour was good at times and we got to know the characters well and quickly through good use of character interactions, but it never really had a proper resolution. There were too many loose ends that weren't tied. We're introduced to so many characters and yet none of them had a true affect on Eun-Ji or Sun-Yeong. I thought there was going to be at least a legal dispute between the construction site and the couple and more at stake for them, but somehow none of this is addressed.
I enjoyed the majority of the film but I was really disappoined in how it ended. It just seems incomplete to me...
