Mercury is an intellectually stimulating film with carefully added layers that traverse through genres, something that is now a fixture with Karthik Subbaraj. Another creatively inclined lead role who ‘defeats his limitation’ — Karthik now has a definitive theme. Mercury is definitely an interesting visual/aural spectacle. It takes guts to make a film where everything isn’t spoon fed. There’s a lot of brain but not enough heart — that makes Mercury, a tad cold. Nevertheless, if you’re watching Mercury, then do so on the big screen. Some good visual/sonic filmmaking awaits.
