Stunning CGI but a confused story

Rating: 6/10 (17 August 2013)

While the CGI and sheer spectacle in Oblivion made it a must-see for me as a SF fan, I found the plot quite confusing, even after having seen the movie in the theater and at home, and having read the Wikipedia plot writeup carefully at least twice. The "memory wipe" doesn't make a lot of sense, and the use of clones in the movie adds to the confusion.
Which is a pity, as the movie had all the trappings of a great SF movie, but the incoherent plot downgrades it to only "good".
However I do laud director Kosinski's aim to make Oblivion "not dark" -too often "sci-fi" is associated with "horror", a real turn-off for me -some sort of echo of the "mad scientist". Let's see more SF movies where the emphasis is on the former.
Still I'm more than happy to add Oblivion to my extensive SF collection.
