Do you think that Horror films are afraid of truly invoking a nightmare for fear of being called "Disjointed/Sloppy"?
As a fan of the genre, and as someone who's enjoyed it's huge rise in recent years, I do think that something that's not being tapped into as commonly is making your film feel as random, chaotic and ominous as a nightmare.
What I mean is to have certain things happen without any kind of easy explanation, to have us go from scene to scene without clear connective tissue almost like a dream, and to have even the scares feel alien to the viewer, rather than a clear case of something we've seen a lot before. I'm thinking of this being the case even in "normal scenes".
There's only been a film or two where I've noticed this being the case, as even the best horror films are clearly coherent from start to finish, there's some sort of explanation to everything we see unless it's purely symbolic and the scares we do get feel either like they could happen in reality or they're stuff you've seen in other movies.
Beau is Afraid is one example of a movie that seems to almost fully embrace the feeling of a nightmare and there are probably more examples that could be named, but it doesn't feel very common. But given the general audience responses to that film, I feel like mainstream horror movies don't quite want to embrace that feeling because it could be mistaken for or perceived as being poor writing/editing/directing.
I think audiences are more equipped to handle things like that today and I'm not saying that movies need to do this all the time, but I think if you create an investing, well made and well acted movie with good characters, you can take the chances for the plot to be hard to digest and even come across as nonsensical. And it doesn't have to literally make no sense, it just has to throw you off and make you wonder what the hell is going on.
I say this because I was rewatching parts of the 2009 horror/thriller The Box. Audiences hated it, critics weren't very kind either, but there's some effectively nightmarish parts of that film and most notable is how the male lead is basically kidnapped offscreen and when we see him again, we have no clue what happened to him whilst he was kidnapped. He just walks out of a building that emits a white void and looks exhausted whilst being dragged off by a couple of soldiers. Then, we don't see the scene of him being reunited with his wife or what exactly happened to said wife, we just see them both being dropped off at their house by a black car seemingly the next morning.
Not that The Box doesn't explain things, but this part of the film lacks much in the way of detail. We see the setup with Arthur and Norma, but the in-between is stripped away and barely recapped before we get to the ending. I'm sure some critics and audiences were baffled and felt we were missing scenes, but beyond the fact that it's not too hard to put the pieces together, the lack of direct clarity in context to the film's plot IS scary. And it was widely released 30 million dollar movie with recognisable stars attached to it, yet wasn't afraid to occasionally feel alien and nightmarish. Hell, I saw that film as a kid, and the Santa scene has always stuck with me as being something incredibly weird and creepy.
I'm sure some commenters will be able to think of movies that do what I'm talking about, and please suggest them to me. And I'm not trying to bash this current golden period of the genre, I just think that more chances could be taken by filmmakers in making their films feel unstable and all over the place in a deliberate way.
