synth-ruiner Brazil - Sure, that's one way to look at it.
Sometimes - many times, I find some films look very scientific on the surface, but underneath is pure fantasy or superstitious fairy tale. Well, those are sci-fi for some but to me "proper" SciFi represents more than a fairy tale in technical looking environment. I think Star Wars is good example of this.
And let's just state the obvious: Is some piece of cinematography ruined if it doesn't fit some category or definition? No. Of course definitions can be fun and interesting to some degree, but they also quickly become irrelevant and boring. A good film is a good film, good music is good music and all that is very subjective.
