Watch 'The 5th Wave' Star Chloe Grace Moretz Fight For Survival — EXCLUSIVE VIDEO

2015 was, by all accounts, a huge year for dystopian YA film adaptations. Divergent and The Maze Runner both released the next films in their respective series with Insurgent and The Scorch Trials, and of course The Hunger Games ended its saga with the release of Mockingjay: Part Two.

looks intense to say the least, as if The Hunger Games, War of the Worlds, and Invasion of the Body Snatchers had a big-screen baby.

But even with all the death and destruction going on, perhaps the most intriguing aspect of the film is the relationship between Cassie and Evan. She doesn't know what side he's on or what his intentions are, and has no idea whether or not she can trust him, but she has no other option but to accept his help if she wants to find her brother. It's probably a good rule of thumb not to trust randos you meet in a post-apocalyptic society, but when you're not even sure if that person is human or not, it kind of adds a whole other element to your decision making.

That internal struggle is on display in the exclusive clip below, where Cassie runs away from Evan in the woods only to be rescued by him from prowling Others. Although it isn't
