Interesting that you mention Dune here. I have a similarly strict approach to classifying works as sci-fi for myself as OP and Dune is the worst offender of everything I consider sci-fi.
To me, Dune is some new-age mumbo jumbo. It's fanatasy in space. Or it is contemporary social criticism (the whole thing is a metaphor for the oil industry, no?), but it's definitely not sci-fi.
By the way, I loved the first half of the book. The world building is fantastic, the characters are interesting (and the villains are really villain-y) but after the Duke dies, the whole book goes down the toilet and becomes a series of random adventure-in-the-desert encounters that couldn't be more shallow and predictable.
That being said, I'm probably too young to get it's larger impact on the "genre" (I heard that it's something like the defining space opera?).
Pretty much the defining space opera, yeah -- I mean, it's set in the year ten thousand, what else can you fairly expect it to be? While I quite like it (and can't abide its sequels), I do concede it takes a peculiar taste to appreciate it on its merits.
the whole thing is a metaphor for the oil industry, no?
No, not really, or at least I think not deliberately; it's much more Lawrence of Arabia in space.
