Watch without any preconceived notions.

Rating: 8/10 (1 January 2019)

When viewing this at the cinema at the start of 2018, the audience's response alone made this endeavour worthwhile. The tone is set by the character's noise restrictions to the movie's premise and the muffled audience reactions in-turn to any highlight throughout.
An original tension-grabbing film that is not justified in dismissing it as simply "boring" or "stupid". Granted it has it's flaws, but I found the 1hr 30min runtime a refreshing change to the usual 2 hour standard these days.
