“The 5^th Wave” comes to us not long after the conclusion of “The Hungers Games,” and it is the latest in a seemingly endless line of young adult book to film adaptations. As a result, I came into this movie feeling worn out even before it started. While the novel it is based on, written by Rick Yancey, might be an interesting read, what unfolds onscreen feels like the same old thing. Only the names and places have been changed to protect the filmmakers from potential lawsuits.

Chloe Grace Moretz stars as Cassie Sullivan, a young teenager (is there any other kind?) who lives a normal life with her family, attends high school where she’s a cheerleader and constantly deals with unrequited love like any other child held prisoner by adolescence. But suddenly an alien ship, which looks like something out of “District 9,” appears in the sky, and the Earth goes through four waves which leave it decimated and on the verge of extinction. All Cassie has left is her brother whom she ends up getting separated from, and from there she is determined to save him from a fate many others have suffered.

This movie does not get off to a good start as the visual effects used to convey the various waves are shoddy CGI, and some scenes end up looking like outtakes from “Independence Day” or any other Roland Emmerich production. When the plot finally gains momentum, Cassie finds herself on the run and forced to defend herself in ways she never planned. She’s also looking for her brother whom she is very close to. Doesn’t this sound like something we just saw?

It’s a shame because the movie does have Moretz who makes this mess more bearable than it should be. Her breakthrough performance in “Kick-Ass” was no fluke and she continues to do strong work in each film she appears in, regardless of whether they are good or bad. She makes Cassie a strong heroine and one whom kids around the same age will easily relate to as she fends for herself in the dangerous world everyone has been thrust into, and Moretz makes you root for her throughout. But even she can’t save this routine young adult movie which has come out way too late.

Actually, what’s especially interesting about “The 5^th Wave” is how the female characters are far more interesting than the male ones. It also helps they have such terrific actresses inhabiting those characters, and each of them clearly relishes the opportunity to bring them to life. Maria Bello, sporting a very funky hairdo, makes Sergeant Reznik a slyly manipulative soldier as she forces the children to see the alien threat her way to where getting them to fight for the human race is easy as cake. Maika Monroe, so good in “The Guest” and “It Follows,” makes her character of Ringer a wonderfully tough warrior, and she also skillfully unveils the other layers of Ringer to show us a person who is deeply broken. Along with Moretz, they keep “The 5^th Wave” from becoming a complete bore.

The male actors, however, don’t have much to work with and their performances suffer as a result. Nick Robinson plays Ben Parish, the high school football hero who, when he is forced to enlist in the military, is nicknamed Zombie. Zombie proves to be an appropriate name as Robinson has little choice but to give a one-note performance as much of the emotion Ben has experienced in life has long since been drained from his psyche. Then there’s Alex Roe who plays Evan Walker, a man who may not be all that he appears to be. It seems like the screenwriters had some trouble in trying to figure out what to do with this character, and that leaves Roe with little choice but to make Evan far more enigmatic than the character has any right to be.

And let’s not leave out the great Liev Schreiber, wonderfully understated in “Spotlight,” as the movie’s main antagonist Colonel Vosch. It’s no surprise Schreiber can give us such a menacing villain, but there really isn’t much of a character for him to play here. Vosch is merely here as an obstacle for Cassie to overcome, and as a result the actor is wasted in a role which is too unworthy of his talents.

Then there is the love triangle between Moretz, Robinson, and Roe, and after having been subjected to a very similar one between Jennifer Lawrence, Josh Hutcherson and Liam Hemsworth in “The Hunger Games,” I could have cared less about it. I imagine it will give audiences much to swoon over, but it’s a romance that is bland as the male characters in this movie.

“The 5^th Wave” was directed by J Blakeson who previously gave us “The Disappearance of Alice Creed,” a neo-noir thriller about the kidnapping of a woman by two ex-convicts. His direction on that film was much lauded by the press, and it makes me wonder just how much control he had over this project. Clearly, the studio is setting this up to be another franchise of movies for young adults to become obsessed over as a sequel to “The 5^th Wave” has already been published and a third book is on the way. But it all depends of course on how this one does at the box office and considering how we are all still getting over the end of “The Hunger Games” movies, I’m not sure everybody is in a rush for yet another franchise like it.

Perhaps the target audience for “The 5^th Wave” will enjoy it the most, but even they have to be outgrowing these kinds of movies at this point. Sooner or later we have to realize kids grow up and become adults, and even adults can save the world and their little brothers too.
