I find this plot structure tired and boring so I'm always on the lookout for movies that don't follow it. They are hard to find! (Also, I probably don't have an excellent memory to recall them later when I do find them.)

Horror movies in general seem to have more freedom to play with plot structure than other genres. Every film, regardless of plot, needs to have something that makes the audience want to watch to the end of the film. With horror, it's often putting the question in the audience's mind "what is happening?" That can be compelling enough to propel the viewer to the end so the film often doesn't need to have a protagonist go through some emotional journey.

It's been a while since I've seen them, but I don't think The Ring or The Grudge follow this plot form. It's probably telling that both of those are adaptations of non-Western films. I don't think Alien follows this structure either: Ridley is basically right all along and just has to survive.

I think Goon is an underrated comedy, and it doesn't really fit the three-act structure well. It certainly has conflict and climax, but Doug doesn't really go through any internal crisis. Instead, he's more often the catalyst for internal change in other characters.
