*The Long Walk* has a great premise, and there are stretches where the movie really captures the bleakness and psychological toll of what these characters are going through. The concept is simple enough, but that simplicity gives the story plenty of room to focus on the people involved and the growing sense of exhaustion and desperation.
Unfortunately, it also starts to feel repetitive. There are only so many ways to make walking and talking visually interesting, and the pacing drags noticeably in the middle. Some of the characters are more compelling than others, and a few of the emotional moments feel like they're trying a little too hard to make an impact.
Still, there's enough here that works. The performances are solid, the atmosphere is appropriately grim, and the basic idea remains disturbing even when the movie loses momentum. I didn't dislike it, but I also didn't find it nearly as powerful as I hoped it would be.
Worth watching once, especially if you're a Stephen King fan, but not one I'm likely to revisit.
