It was easy to suspend my disbelief with this movie which I think you have to do more than not when watching a spy/action comedy. This movie isn't perfect but I found watching it a lot of fun. There were a lot of moments I laughed out loud. Kang Ji Hwan has a certain style of physical comedy. He's an expressive actor and isn't afraid to be 'out there', to look silly or foolish. He can also turn it around on a dime and be serious and kind of badass. I dig that about him. Kim Haneul is good....just plain good. She really pulls off the silliness of the comedic moments but she is believable during the dramatic moments too. But this is mostly a farcical story even with all the spy action going on. I will be seeking out other things she's acted in. I'm giving this high marks purely for my own enjoyment and I recommend this if you're up for a fun, easy watch.
