An alien race, only referred to as The Others, has attacked Earth in “The 5th Wave” using different methods to do so. These include cutting off electricity, causing natural disasters and a mega-virus. The film picks up after these first three “waves” with the character Cassie (Chloe Grace Moretz), who is one of the remaining human survivors, along with her father Oliver (Ron Livingston) and her brother Sam (Zackary Arthur).
After an incident at a refugee camp for human survivors, Cassie’s family gets separated and she is sent on the run with the goal of saving her brother. Along the way she begins to learn what the 4th and 5th Waves are, that The Others are using humans as hosts and are tricking other human survivors.
While “The 5th Wave” does use a plot similar to other sci-fi flicks such as “Invasion of the Body Snatchers” and “The Faculty,” it still starts off strong enough. Cassie is introduced as a good protagonist and her tale of survival is engaging and exciting and made the first half or so a solid experience.
