I lived and worked in Korea 8 months as well as visited it several times and my opinion is kinda divided and down to earth I would say. There are good and bad sides in Korea as in everywhere. My current and my ex boyfriend are both Koreans. Through them and my working experience I got to know a lot more Korean culture than most exchange students ever do. I would describe Korea myself like this:
Korea is great for vacation and spending money! There are also always something to do and you never get bored. Also the pop culture is really interesting~ But I have to admit that it won't be a country where I will want to raise my kids and my family... And there are many reasons for that. (if you want to know more about that, ask me-). I call Korea the land of contrasts actually.
Anyway, I don't mean to offend Koreans or Korea here, my message's purpose ain't that! I just base this on my own personal experience (:
