I finally watched this drama after it being on my to watch list for so long. The cast, and the strong reactions from viewers, made this a must see for me. Now, 10 years after the fact, I'm glad I watched it, but I was not impressed. This drama is definitely dated, and I'm not just talking about the flip phones, or horrible outfits. The story itself is a very basic romantic melodrama. All four characters are in an epic love square with all the usual plot points (rich vs poor, obsessive jealousy, mean parents, betrayal, stalking...) and this gets stretched out for 20 episodes, which means there are LOTS of flashbacks. I can understand the idea of having a tough time choosing between 2 men/women you care about, but It was really hard for me to take the romance seriously since I don't think that an abusive relationship with a crazy man is very romantic, even if he's rich and cute. Most of the characters behaved in ways that often seemed ridiculous, and was often frustrating to watch, but I couldn't look away... That's because of the cast. I'll start with my praise of So Ji Sub, who is always amazing. It's no surprise that he was great. He was my favorite of the cast, and super cute (even with the stupid hair choices). He plays the mysterious, and brooding In Wook perfectly. He was the only character I rooted for throughout the show, but I also liked that he had a bit of a dark side... sexy! I'm also a fan of Ha Ji Won, but I'm not used to seeing her play someone so passive. As Lee Soo Jung she spends a lot of the show being used, yelled at, or beat on. Her character is portrayed as innocent, yet money hungry, and was honestly hard for me to like or root for because of her choices. Ha Ji Won did an ok job, but at times was a little too melodramatic for my taste. Still, I did like her chemistry with the two male leads during their few rare happy moments. I also liked her relationship with her Bff. This is my first time seeing anything with Jo In Sung, and his portrayal of Jae Min was certainly entertaining, though definitely over the top. Jae min is super entitled, and completely manic, but somehow still kinda sympathetic. Many of his scenes consist of epic crying, maniacal laughter, explosive anger, and dramatic begging. His "crazy" is the driving force behind the whole drama, so in a way he's what kept me wanting to watch what happened next. The square is completed by Park Ye Jin as the... i'm thinking of a word that rhymes with 'itch'... Young Joo. Her character is subtly manipulative, and easy to hate. It takes a talented actress to portray such an unlikeable character so well. Many of the supporting characters deserve the same compliment. So if you heard anything about this drama you know about the widely 'controversial' ending. I was not upset by the ending, but like much of the show, it was very frustrating. I like that the writers didn't go for the predictable people pleasing ending, and tried something more shocking, but it was still cheesy in a way. I certainly laughed inappropriately. Oh, and the music... I think that the soundtrack was starting to drive me slowly insane, but it's the kind of OST where once you hear a song from it it draws you right back into the drama, so I guess that's a good thing. Overall, I see "What Happened in Bali" as really bad junk food. I would never call it good, but I had fun watching it. I guess my love/hate relationship with this drama fits the theme of the show. It definitely kept my interest, even when the storyline started to drag. I wouldn't watch it again, but I would still recommend it. However, if you are looking for something light and fun, there are very few of those moments, so avoid this like the plague. This is NOT a Cinderella story. If you're looking for something to make you yell, and throw things at the screen, you found it! Plus So Ji Sub is in it, and do you really need more of a reason than that?
