I enjoy the fact that the whodonit genre has finally gained traction again, these many years after clue. Watching this with family allowed for an enjoyable time, with little to complain about. Thinking, searching and calculating during the progression of the movie allowed even my old man, who typically falls asleep to even the most action filled movies, to follow the film actively and consistently. It's long buildup and rather late reveal seemed an improvement to the prior knives out movie, which rushed to a reveal. Finally, the underlying commentary to upper class society was done very nicely, even if the character stereotypes were a little on the nose.
