As many others, I was excited to watch this drama since it was Gong Yoo's return to the drama scene and I'm also a big fan of Lee Min Jung. Unfortunately though, Big didn't live up to its hype. I honestly felt a bit disappointed, especially with the ending. Don't get me wrong, I enjoyed the drama, but it could've been way better than what it actually was. The story itself started off really well. It was entertaining, it kept me interested in the relationships between Gil Da Ran, Kang Kyung Joon, and the mysterious Seo Yoon Jae, and it was really funny as well with much thanks to Baek Sung Hyun. But as the story progressed, I felt that it started to lose its way as there were many filler scenes that could've been used for more plot or character development. They also kept going back and forth with the "to love or not to love" dilemma between the main characters which made the story drag a bit. Although this is common for romantic dramas, this case was pretty excessive and became a repetitive occurrence which started to get old after awhile. The cast lineup was great. For having a script with a story that somewhat lost its way, Gong Yoo and Lee Min Jung played their parts perfectly. Baek Sung Hyun also shined in his role as Da Ran's brother. He's actually one of the reasons I kept watching this drama since he always provided epic comic relief to all the drama going on. As for Shin Won Ho, despite being one of the main characters in the story, he barely got a chance to act at all, so if you're going to watch this because of him, I'd either pass on this one or just watch the first few episodes. In the time he was actually shown, he was great. If he had more opportunities to act in this drama, it probably would've been way more entertaining. And lastly, Suzy. I'm a fan of hers, but her acting wasn't noteworthy nor was it horrible either. As for it's rewatch value, I doubt I'd watch it again. If I did though, I'd probably only watch the first few episodes because that was the best part in my opinion. The last two episodes were pretty disappointing and the end itself wasn't great either. It wasn't the worst I've seen, but it definitely left me wondering what the heck happened. There were many questions left unanswered because they decided to resolve the hyped climax within the last 10 minutes of the final episode. Why they didn't make better use of the last two episodes [or even more] for better closure to the story is beyond me. They had so many opportunities to make this story shine, but instead they let it run out of steam right midway into the drama. I'd only recommend this if you have nothing else to watch. There are definitely some cute and hilarious moments that I enjoyed though and the chemistry between Gong Yoo and Lee Min Jung was great, so I'd say take a shot if you want to see it =]
