It's the follow up to the 2010 movie 'Monsters'. The first was shot on a very, very low budget and the director, Gareth Edwards, edited the entire movie on his laptop!
It's very darkly shot, so you don't see much of the monsters, but they tried to rely on characters to drive it. He then went on to direct the latest GodZilla movie and of course now as one of the Star Wars spin off movies I believe.
