'Oblivion': Sci-fi pastiche doesn't come together, reviews say

These days it seems rare to encounter a big sci-fi movie that's not a remake, a sequel, a prequel or an adaptation of a well-known property (whether a novel, a comic book or even a toy). The new Tom Cruise film "Oblivion" is an exception: This story of a solitary drone repairman on a devastated future Earth grew out of director Joseph Kosinski's ("Tron: Legacy") own unpublished graphic novel.
