This was a funny little movie, but I would judge it solely on the comedy and not the 'mystery/thriller' side. The mystery/ thriller parts really cannot be taken too seriously, otherwise you may think the writing is lacking. I enjoyed all the actors, especially Ha Ji Won. She and the actor playing Jason speak a lot of English, and do so very well. There were several laugh out loud moments for me while watching this. It was an enjoyable Sunday afternoon watch. (I don't usually review movies, but wanted to add this one since no one had reviewed it yet.)
