I decided to give this drama a try for two reasons: because it was a comedy and because of Lee Hongki, whom I had already seen and loved in You're beautiful (besides the fact that I'm a huge fan of him as a singer). At the beginning I found his character really funny, but later on I actually wanted to slap him. Not his fault, but the writers's fault, obviously. In fact, it's Lee Ha Nui's acting that was actually a nice surprise. Well, I had already seen her in Pasta and I didn't dislike her performance, but her role in MF is so different that I really enjoyed it. The pairing is a little weird in my opinion and I don't think they had any chemistry at all. I guess that's one of the main handicaps in the story. I actually had a strong case of second male lead in this one, to be honest. In fact, there are many other more interesting and funnier couples in the drama, like Kwak Dong Yeon/Han Joo Hyeon, or Seo Dong Won/Jung Shi Ah. These two were really funny and I actually enjoyed Seo Dong Won's performance a lot. Also, I liked AOA Mina's performance. I admit I don't usually expect much from idols's acting, but I think her role suited her and she was funny. I think the drama is overall well casted. One of the strongest points of the drama, in my opinion, are the female characters. They are pretty unusual female characters for a drama: a single mom, a swindler, an ex-unfaithful girlfriend, an idol... even a non-Asian wife. Even if in the end the same usual clichés end up resurfacing in the plot, and Han Bo Reum's character, for example, becomes the typical annoying second female lead. Also I found the plot original for a drama, and I appreciate that it's not set in Seoul, for a change, and that it doesn't involve the typical chaebol/working class hero or heroine romance/s. The humour... well it might not be everybody's taste, since it's a bit coarse at times, but it's pretty funny all in all. As for the soundtrack, I don't usually like it when dramas use cuts from non-Korean songs, because they overuse the same songs drama after drama. It sounds too patched up to me. I prefer it when soundtracks are original and recorded purposely for the drama. I understand that at times they wanted to create an especific atmosphere since the plot is about a rock band, but either way, the choices could be much more original. The plot development is sometimes uneven and it doesn't focus too much in romance, but either way it's an endearing story with quite endearing characters and I recommend it.
