Beau is Afraid was the last one I recall. I think it was mostly the latter half of the movie where I started to get a bit confused and needed the ending explained to me.
What movies made you look up some kind of explanation afterwards? I feel like I have done it several times in the past for more surreal movies but can’t think of any other examples.
It can also be a TV show.
The Arnold film (subtly) tells you that it isn’t real. In the beginning, when they are prepping Quaid for the implant, one of the technicians remarks “That’s a new one… Blue sky on Mars.” At the end of the movie, bam, blue sky on Mars.
There is zero chance that anyone could predict such an event, and no way for Hauser to have known about the reactor or what it would do. Hauser’s mission was to infiltrate the rebels and get to Kuato.
There’s a lot of other circumstantial evidence, and you could probably explain away a lot of other stuff. But the fact remains that nothing can’t be explained as part of the dream, and there’s one thing that can’t be explained as real.
