If you've been watching Korean movies and dramas long enough, you must be familiar with Park Sung-woong, as he is usually cast as villain, gangster (just look at 'New World'), or as a common ahjussi.
I never expected it would be this fascinating to see Park Sung-woong's fresh character. Seriously though, Park Sung-woong in this movie is so precious, maybe we won't be able to see it again in the future.
Alongside Park Sung-woong, there are Jinyoung and Ra Mi-ran.

The Dude in Me has some absurd scene due to being comedy genre and there are too some "dear viewers, please cry!" moments but it doesn't really succeed as I'm not symphatized enough. The emotions feel kind of shallow and the chemistry between the characters seems off (Jinyoung proved me he's a decent actor though but the chemistry is just...). However it's still bearable and I'm here for the comedy anyway so it's forgiven.

In conclusion, The Dude in Me is a good comedy movie, it accomplished its purpose of entertaining the viewers. Maybe you too should give it a try?
