A film based on a series of young adult novels, which is a sentence I've written at least 100 times in the last four years. It stars Chloë Grace Moretz as a teenage girl who... you know what, it doesn't really matter. It's a dystopian future with fighting children, and she's the one who's got the pluck to bring the whole thing down, and maybe love-triangle some hunky male teens while she's at it. The title refers to all of the steps that a group of aliens must take to kill everyone on Earth, and it's an awful lot of steps for such a master race, especially once you get to the eponymous fifth wave, which is an all-around terrible plan. If I get much more into the plot, you may have some of the same questions that I did, such as: Why? And, what the hell? And can't she tell those people are obviously aliens?? by Elinor Jones
