Just came back from seeing this master piece, I would have to agree with what RADIOACTIVE MAN said. The movie was excellent and the plot twist was definitely better than the plot twist on Iron Man 3. While IM3 was enjoyable and entertaining, Oblivion is certainly a better movie as a whole. The sequence in which the story develops was perfect, in the end everything was explained.
