Story wise this dorama doesn't reinvent anything. As a procedural it isn't done well. It tries to surprise us as times but doesn't work all the time. However, since it Never takes itself seriously, all this doesn't bother you and you feel its all done on purpose. Some episodes, specially early on, weren't that great, while others were pretty thrilling. The main premise was our father-&-son duo who haven't been in contact for a while. The son does have some parents issue but doesn't let it control his life and, when he gets the chance, expresses himself clearly. His personality is extremely cute. You just believe in his shyness & awkwardness. The dad might appear as a bully, but you can see his affection for his son. You can feel some hidden pain that he avoids with his silliness. He's a weird mixture of pettiness and cool, making his character most fun. The other characters aren't too important but add a nice touch to the mixture. Some of the episodes concerning their characters were well made. The girl in the group was alright. She didn't bother me throughout (except her acting stupidly in that 1 episode). The crush the dorama was hinting on the part of Sahara-kun was cute too. It just welcome spice to the mixture. The villain of the story is 1 dimensional and just here to make the main characters' life harder. He's still creepy enough to keep you on your toes. I liked the music and the action scenes here as well, though not a fan of our leads' signature move, they make it work ;) Overall entertaining, easy to watch on stressful days, fun to watch on depressing days.
