Incredibly good, slightly bad

Rating: 7/10 (15 February 2020)

Clever feel-good movie that transcends into Horror / slasher genre - similar to Hitchcock's Psycho.
Limitations - Plot problems:
1. Kim family members are cunningly talented & smart - yet have the most menial of jobs.
2. Papa Kim's motivation to kill Papa Park is implausible.
3. Detectives in Korea are apparently useless - can't find Papa Kim.
Benefits:
1. Suburb film making - pace / rhythm / continuity / acting / montage / symbolism / editing / cinematography
2. Consistent Theme of a sons love for his family/father (even a flawed father) and toiling to bring prosperity to his family.
