Gu Family Book is a great historical drama to get lost in. It didn't even feel like it was 24 episodes long. Sure, it's another Gumiho story staring Lee Seung Gi, but it's completely different from My Girlfriend is a Gumiho (which I loved FYI). Though there's a familiar theme of star-crossed lovers, Gu Family Book is more of a fairy tale, and Choi Kang Chi's story at times feels like a superhero origins story. From start to finish I was completely hooked on the story, and the characters. The story centers around 2 ill-fated loves. I thought both stories weaved together well, without feeling too cheesy, or forced. Gu Wol Ryung & Yoon Seo Hwa's tragic romance had me hooked from the very beginning. Choi Kang Chi & Dam Yeo-Wool's chemistry kept me excited about what would happen next. I'll admit that the story was a bit predictable at times, and there were a few frustrating questions left unanswered (specifically about the Gu Family Book), but the amazing cast made every episode enjoyable. At no point was I ever really bored. Lee Seung Gi is one of my favorites. I've loved him in every drama I've seen him in, so it was great seeing him in a role where he gets to evolve into a true hero. He was perfectly complimented by Suzy, who plays a strong heroine, not just the pretty damsel in distress. They worked well with each other, and even made some of the cheesier love moments work. I think the entire cast did a great job, so it's hard to single any actors out, even though I did have a few favorite characters. I hated who I was supposed to hate (Lee Sung-jae is such a good villain), and empathized with the entire colorful cast of characters. I also loved that many of the characters, weren't completely good or bad, which gave them more depth (Choi Jin Hyuk looked so good being bad, and Jo Jae Yun was hilarious). Though they played 'over the top' at times, I had to give the cast a 10. The script I think was a bit too ambitious, which Is why I gave the story an 8. I don't think there were many plot holes, and I can forgive predictable stories if they are entertaining, which this was. There were actually a few moments that caught me completely off guard, and that kept the feeling of suspense going. I do think that some of the explanations were a little too far fetched, which made it hard for me to connect emotionally. I did not cry during the "sad" parts, because they were so melodramatic. Still, I was completely invested in the characters, which I think is a testament to the outstanding cast. I did not love the music as much as others did, but it did compliment the mood well. I could see myself rewatching this, and still being entertained, but I wouldn't call this drama one of my favorites. The ending does leave the door open for the possibility of a sequel, which is an exciting thought. Overall, I would say this is worthy of any Sageuk to watch list. It was not perfect, but it was exciting, and enjoyable enough to get a "great" score from me. If you are willing to suspend your belief, I think you'll enjoy it too.
