My feelings on this couldn't be more mixed.
Blade Runner is my favorite movie but, on the face of it, I don't have any particular interest in the idea of a sequel. Meanwhile, the people involved in this production (Fancher, Villeneuve, Deakins, Scott) appear to be about the best/most potentially-interesting one could hope for.
So...
I guess I'm looking forward to it with sheer trepidation.
