I recently watched The Batman, and while I love epic three-hour movies as much as the next guy, the film felt like it was wrapping up when Falcone was murdered. Then BAM, there's a whole other hour. That moment felt like the perfect climax for the movie, then tag on that motorbike resolution between Batman and Catwoman, and it would have been a great two-hour movie.
Any other films that could be a full hour shorter? *doesn't have to be a three-hour epic.
