This was a fun drama. The cast was fantastic, there isn't anyone that I thought shouldn't have been there, or didn't do a satisfactory job. Siwon in particular was so willing to make fun of himself, and be as stupid and over the top as possible, and it was hilarious. Good job Siwon! He basically carried the entire humour for the show. Maybe there were a couple of characters that could have done with some extra development (Sung Min Ah in particular), but that's the writing, not the acting. The music was very pretty. There was one song that played during the scenes between the two leads, and it was very fitting. Not necessarily the lyrics, but the music. It just seemed right. They had a lot of digs at the Korean entertainment industry. And I mean, a lot! After all, it's set behind the scenes of a TV drama, and boy, do they milk everything they can from that! I loved all of the references to little things we have heard about, but haven't seen criticised so heavily in a drama before. Like the end of year awards going to the actor/actress/show with the highest rating, not the person/show who actually deserves it. I think the extension got to them a bit, and the ending was maybe a bit... silly and predictable (although not unexpected). But overall, a good watch.
