I recently watched Oblivion and was pleasantly surprised by how good it was. By no means an original movie, indeed it uses many themes and tropes from many other sci fi movies. But like the director's other movie (Tron Legacy) it does feature incredible art direction, sets and vfx seemlessly blending "in camera" effects with cgi
Here is one on the drones that appear throughout the film.
