Binged seasons 1 & 2. Fantastic show! Season 3, however, was kind of too dark for me. Apart from having forgotten to note all the characters' names to finally get the who's who after months, the plot simply turned out to be too DARK, depressing even - at least for me. Ugly faces, extremely bad mood 99.9 % of the time mixed with a bit suspense plus a dissatisfying end that led to the conclusion that I rather should have watched another k-drama!
