Mutual distrust turns to uneasy alliance as an alien invasion forces a group of British teens to work together with a nurse who they mugged in this action thriller starring John Boyega as the leader of the teen gang. Boyega is just as effective here as in 'The Force Awakens', giving his hardened character a vulnerable, human side bubbling beneath the surface. The actors who play his young friends are well cast too. Jodie Whitaker is less effective as the nurse and Nick Frost is criminally underused, but in general, there is a lot to like about how the characters interact here. There are even some scattered comic moments to be had in how everyone from the teenagers' girlfriends to the local teen drug lord scoffs at their claims of being under alien attack. The gradual bonding between Whitaker and the teens, who she initially describes a "monsters", in the face of *real* monsters is where the film succeeds best though - so much so that the action sequences end up being a low point of the movie. Without any eyes and glowing sharp jaws, the creatures are quite unsettling to look at, but all the attack scenes become a little repetitive with the film sagging towards the middle. The movie certainly ends on a very high note, however, with a third act that potently pushes the film's single biggest message about teen thugs always being misunderstood and never properly recognised.
