User Reviews

better than the original in comedy
20 May 2017 | by fluffsetSee all my reviews

Anyone who have watch the original one from Japan in 2012 may like or quite dislike this remake. But me, who really love the original one really like this one too!

The original one by Kenji Uchida is perfect, its well-balanced in comedy, crime and drama with its smart story telling. This Korean version just take the main idea and change the whole story quite a bit but its really good and enjoyable. What I love the most is their focus in the comedy, even though the original one have its funny moment too, the Korean version have take the advantages of the body swap situation to make it more funny and hilarious to watch. This movie make me laughing out loud a lot. Its more lighter than the original one but I bet if you watch both, you will like all of them. Enjoy.
