First off, why do all the reviews here, even the negative ones, praise the music score? The score is the epitome of booming trash that director Christopher Nolan regrets popularizing in Inception (2010). The main reason the audience is on edge the whole film is because the music is so overbearingly ominous even in scenes where nothing ominous is happening.

The screenplay is more fitting for daytime TV. The dialogue and acting is average, not bad, but also no memorable lines or deliveries. The plot is littered with cliches, inconsistencies, and people acting way dumber than they should (even in terrifying situations).

However, with all of that said, the movie is still compelling enough that I never wanted to stop watching. Aside from the incomprehensible quick cuts in the intro, I have to give the director kudos for setting up some compelling cinematography and making the most out of a bad script.
