This was one of the dramas that started off boring but picked up as it went on. The format is somewhat new and experimental for Kdramas since it follows a documentary style narration. I liked this drama because it was fresh and had a lovely cast. It has a story and at the same time it doesn't. It's more about being a PD and the relationships and challenges that come along with it. All the while I kept thinking "Wish I worked at KBS!" What sets this drama apart is that everyone is likable. There are several side characters that make an impact along with the main characters. The cast had great chemistry and they seemed to gel really well. For me this drama was largely enjoyable due to the references to the current pop culture of Korea. The references to variety shows, idols and the cameos- OMG! It had me squealing out loud with laughter. There were times this drama was a typical Kdrama. We have a love square here (like always) but for me it was a bit difficult to guess who would end up with who. Wish they had focused lesser on that and had continued the same format it had for the first 7 or so episodes. After that the drama became a bit repetitive at times. It felt like the writer had no idea what to do with the story later on as the drama is so short. 12 episodes is way too less for me and I felt like so much more could have been explored had it been 16 or 18 episodes. It's kind of unfair, if you ask me. Anyway, the cast is lovely and IU really surprised me with her acting. She was terrible in the beginning but she grew on me as the story progressed. Her character has the best growth out of all. Plus I loved Kim Soo Hyun in this. I normally don't like him (yeah, throw stones at me) but here he was hilarious. Gong Hyo Jin & Cha Tae Hyun were wonderful as well. But really- Kim Soo Hyun is the one who entertained me MOST here. Also the cameos like TaeTiSeo, JYP, Hani, Dara, etc. was a true treat to someone who loves kpop. I like the OST as well and I would recommend the song 'And One' by Baek Ji Young for a listen. Wish there would be a Season 2 and I can probably be satisfied for real. Anyway, I am glad I watched this drama.
