How Memoir of a Murderer was received

The arc
A solid box-office hit in Korea in 2017, it later found a second, wider life on streaming, where it became a fixture of 'best Korean thrillers' lists for international audiences discovering K-cinema post-Parasite.
What’s debated
The debate is all about the two versions: the theatrical cut versus the longer director's cut ('Another Memory') with its altered ending — fans genuinely disagree over which one is the 'real' film.
Its footprint
It travels as 'the Korean thriller about a serial killer with Alzheimer's' — an irresistible one-line pitch that gets it endlessly recommended in K-thriller threads, usually alongside a Memento comparison.
Where it stands
A dependable mid-shelf favorite of the Korean-thriller wave — not top-tier canon like Memories of Murder, but a 'trust me, watch this' pick that keeps circulating on watchlists.
Did you know? It's adapted from Kim Young-ha's bestselling novel, and just a few months after the theatrical release a director's cut with roughly 15 extra minutes and a different ending hit Korean cinemas — effectively giving audiences two competing versions of the same film.
