I loved this film...from beginning to end. Story- It wasn't a completely original or necessarily a new plot but the execution was almost flawless, each character was individual and unique. The story spent a long time in the past, and it worked because we got to know them in the past before we saw them in the future. The only downside and its not really a downside, is maybe they could have made it a little longer so we could understand their lives a little better. Acting- Just great! I don't really know Kang So Ra so I'm not biased but my favorite character was Sunny's leader Ha Chun Hwa she's feisty and loyal. Music- I loved all the 80's music... surprisingly even though they were American songs they worked really well. They made the scenes funnier at times, and more touching. I'd watch it again, and if you're considering whether to watch it definitely do. It's not too heavy, but its touching enough to leave an impact, but not the type that makes you feel depressed but the type that makes you feel like seeing all your friends.
