Unfortunately i think Ridley Scott is right. Just google "100 top sci-fi films" and most of the lists results have very few movies made since the year 2000. Minority Report, and the remake of War of the Worlds being a very few examples. Personally i think sci-fi was reborn in literature at least, in 1984 with the publishing of William Gibson's Neuromancer novel, thus igniting the Cyberpunk movement from which we have Ghost in the Shell (anime) and the Matrix (1st movie).
