I haven't seen it, and probably won't, as we just don't go to many movies anymore.
In the popup ads on the www, the Paul Atreides character looks like a hermaphrodite. Not that there's anything wrong with that.
But I don't know why these film adaptations of Dune (I'm thinking also of the 1984 version by David Lynch) seem to need that character to be of ambiguous sexuality. Kyle MacLachlan is a "pretty" boy in that one. (That does seem the norm for David Lynch from what little else of his work I've seen.)
In reading Dune, Dune Messiah, Children of Dune, and enough of God Emperor of Dune to know that I had had enough, I never thought that Paul Atreides was anything other than an unambiguously straight male.
Or maybe that was there but it was just too subtle for me.
