Psychological thriller meets black comedy. “Bittersweet Hell” is wonderfully staged in many ways. The script may have its weaknesses here and there, but the performance as a whole quickly makes you forget about that. Lee Hye-young clearly steals the show from Kim Hee-sun here. However, it's hard to top her fantastic performance as the eccentric mother-in-law (which alone might make a rewatch worthwhile...). Together they form a resolved mother-mission-duo, both determined to fight the 'WE' of their family, in which they feel deeply at home… even if this 'WE' might have plenty of flaws... Eventually, the cast is also hand-picked in other ways, e.g. with KPop Idols Yeonwoo, Jaechan and Chansung. Overall, I´d say “Bittersweet Hell” offers unique KDrama enjoyment.

The plot is centered around the psychological phenomenon of so-called 'invalidating communication', which is also known as 'gaslighting' – after the play "Gas Light", which became particularly famous in the 1944 film adaptation "The House of Lady Alquist" with Ingrid Bergman. Gaslighting is about deliberately and consistently misleading a partner, family member or close friend. Gaslighting only works among close ones, i.e. trustworthy people. Thus manipulated with psychological tricks and lies, the victims feel increasingly insecure when it comes to their own perception, ultimately preferring to entirely rely on the supposedly valid judgment of their trusted person… who is now able, to fully control his/her victim. In "Bittersweet Hell" various examples of this phenomenon add to the plot dynamics. In passing, the KDrama also explores other socially explosive topics – above all the high value and ideal of ´family´ versus the sobering reality of ´actual family lives´, but also the weal and woe of the mother's role, different parenting styles and sexual orientation.

In my opinion, "Bittersweet Hell" could have used the 16 episodes (there are only 12) in order to better develop some character profiles. The effective production and performance, however, is actually very well making up for some lack of substance here and there. Therefore I´d consider this criticism a suffering on a rather high level… because nevertheless, “Bittersweet Hell” comes along as a great psychological thriller about gaslighting and family, wonderfully wrapped in the cloak of a black comedy.
