Predictable?

Rating: 8/10 (28 September 2013)

I just wanna start of by saying that I gave this movie an 8 out of 10 because the graphics, special effects, and animation was all done very well. But am I the only one who watched the trailer for this movie and basically knew almost everything that was going to happen? (WARNING: Spoiler ahead! Caution when reading if not wanting anything spoiled!)
The only things I did not get from the trailer were that 1. The alien/ antagonist would be a floating cube thing, 2. That there would be clones or alternate universes of them (Jack Harper & Victoria or whatever), 3. That Jack Harper would die in the end, aka the main character dying...
I thought the movie was creepy, entirely possible, and I thought it was kind of weird/ maybe stupid that they didn't let the drone with the bomb go, could it not fly? Like, why did they have to take it outside? Personally I thought after they put the nuke in that a hatch would open from above and it would fly out. So I don't know why all the drones had to come and people had to die and everything, probably because they needed to add more conflict, more drama and more time. And I got really confused because they didn't really make it clear what the clones/ alternate universes were all about, how Jack Harper is 'a weapon' / where he came from? Or how the conflict started? I'm not really sure what they were talking about at that point... Or why they ejected the people that were in deep sleep when they were entering the cube....
So overall I thought it was good, just creepy and confusing. If you've watched Oblivion, what were your thoughts? How did you like this movie? Please comment below or make your own review of the movie.
Thank you,
