I wasn't sure what to expect from this movie, but this wasn't it. I had heard that it wasn't the comedy the trailers led me to believe. But don't get it wrong - there ARE some funny parts. There is also a LOT of profanity, but oddly, it didn't bother me that much. Jo Jung Suk and DO both did an amazing job acting in this. JJS wrung all the tears out of me in the last third of the movie, and the ending song sent me over the edge into a sobbing mess. This is brotherly love. I had no idea I would be so moved by this movie, so I wholeheartedly recommend it.
