IDk if "serious" is a good bar, but I feel the opposite is true.
First, there are a lot more books than films... and some deal in very interesting ideas. Second, I feel like we're in a new golden age of sci-fi right now. 1950s part 2. Even in the blockbuster film/tv category, there are lot more interesting & creative ideas happening. I thought "her" was very innovative, both in film making and in ideas explored.
Westworld did do a good job of building up fictional theory of conscious machines machines.
