"It Ends" centers around a group of four friends: James (Phinehas Yoon), Day (Akira Jackson), Fisher (Noah Toth) and Tyler (Mitchell Cole). They go out to get food, but with one wrong turn, they end up on the road trip from Hell. Well ... more accurately, they end up in purgatory, on a never-ending two-lane road to nowhere.Why you should watch it: I loved this movie when I saw it at the Atlanta Film Festival last year. It ended the year as one of my 10 favorite movies of 2025. It starts as a jump-scare horror flick but then transforms into a more cerebral psychological thriller. The sound design is also a high point of the movie. There's a droning sound in the background that, combined with the score, builds throughout the movie and creates incredible tension.Buy or rent "It Ends" on Amazon nowSign up to the weekly Tom's Streaming Guide to stay in the loop with the latest releases and top recommendations across your favorite streaming services.
