Collider's 10 Movies That Are Very Hard to Finish

"Once you start any kind of story, it's best to see it through until the end, especially if you want to come away from something with a full-fledged opinion & all. Some might deem it fair to cite a lack of interest in finishing something as a flaw, but things can turn around as stories progress, & a great ending can elevate a merely middle-of-the-road piece of media to a genuinely good one. Movies tend to be shorter & easier to consume than say TV shows, books, or video games, so as a medium, it's generally easier to finish films than those other long-running ways of telling stories. But some movies, because of length, confronting subject matter, or general slowness can be harder to finish than others. These examples show that even great films can prove challenging to finish (or watch in one sitting), because everything here – except one – can be called a good film. They're all challenging and require some level of endurance to get through, not necessarily a bad thing." - collider.com
