The original movie was done by the Italian, which in my opinion is the best. The Spanish then did a remake a year later & then this Korean version came out, yet another year later. I actually prefer the Korean version to the Spanish version, as I feel that the chemistry between the Korean actors are much better. My verdict being the Original Italian version being the best, followed by this Korean version & lastly the Spanish version. Go check out the other two versions of the movie, if you haven't done so.

1) Italian version - Perfetti sconosciuti (2016) 2) Spanish version - Perfectos desconocidos (2017)

It's popular for original movie not a long time back, the story is exactly the same just the dish and mode of phone used. No point to replicate something and taking credit form the original. And the most important is it's not better than the original.

The original movie is only made on 2016, two years later, you're remaking it? The only reason i gave 2 two stars is because it's remaking a good movie, or else why spending so much money to film a same movie.
