As someone once wrote about Lem's heritage and making it into cinema: Solaris is the only one with enough sexual context to show to the viewer, other works just do not have enough of it.
I'm just rephrasing this from memory. The audience may be different now and possibly can accept less sex (this is supposedly a new trend in cinema).
