A technical marvel, one of the best shot Tamil films in recent memory, with a surprisingly adept sound design that compensates for the lack of speech in creative ways
In Mercury, the lack of speech functions purely on the level of a gimmick. Fortunately, the director has enough tricks up his sleeve to make the scary portions work.
It's a straight-up horror film and the director should have taken more care towards delivering the chills rather than a half-baked save-the-planet kind of message.
The movie is a mess, yet once the thriller plot kicks in, you do start to absorb it as a "silent" film, tuning into the visual atmosphere of stalker fear and rusty chemical entropy.
