2020's "Tenet" isn't the first time that acclaimed filmmaker Christopher Nolan dabbled in science fiction, but it's arguably his most confusing attempt at the genre. Its ending – and everything else preceding it — is as baffling as it is intriguing, and that's mainly to do with the film's take on how time travel works. After the Protagonist (John David Washington) is recruited into a shadowy organization called Tenet, he learns that time travel is real through means of inverted entropy, or items that are traveling backward through time. It's not exactly the simplest thing to grasp, and it's definitely something that demands repeat viewings.
Nolan's refusal to handhold is almost part of the appeal of "Tenet," however, and it adds to how ambitious the film can oftentimes be. It's not exactly the digestible crowd-pleaser that "Edge of Tomorrow" or other films on this list are, but it does feature trademark Nolan action set pieces that must be experienced to be believed. Love it or hate it, "Tenet" is a sci-fi movie that every fan of the genre should at least view once in their lifetime, preferably on the biggest television they can find.
