Honestly, it’s a good movie. One of the better adaptations of a sci-fi story to be honest. Ellison was directly involved, which is why. The only complaint I can make is the same big one Ellison made- they changed the last line of the story. The only other big change is that Vic is older in the movie than he was in the novella.
Edit: If you’re a Fallout fan, you should definitely watch it, because it was one of the inspirations for the look and feel of the games.
