I have rarely seen the ratings so varied as they are here for Doona! Reading through the reviews, the bad ratings probably come mainly from young and immature critics who didn't understand the ending (although you can watch a scene multiple times on Netflix) and who wanted the story to develop as they wished. Then we have a lot of psychologists among the viewers and those who can't step outside of their culture. Anyway - I liked Doona! and I liked Bae Suzy's restrained acting, she gave many scenes a deeper meaning with her facial expressions. I was actually prejudiced about seeing another drama with her after the really, really bad "Start-up". But she managed the broken character quite well!
