It’s hardly Citizen Kane, but as feature debuts go Monsters is a pretty impressive feat by another multi-talented wunderkind: Gareth Edwards wrote the script, directed the film, was his own director of photography and did all the CGI on a computer in his bedroom, bringing the film in for cinematic peanuts. It certainly looks as if it cost a whole lot more, making the most of its Central American locations with some impressive cinematography and seamless, understated effects work. Looks, though, aren’t every-thing, and one of the film’s surprises is its refusal to rely on visual effects to tell its story; they are subtle, sparing and never used for their own sake.
