Oblivion

Did I miss something here? The film about a pilot/soldier/something who is overseeing the removing of Earth's last resources after an alien invasion devastated the planet and population (PS the only commercial I saw gives away a hunk of the plot) doesn't seem to have much point to it. There just isn't anything groundbreaking, action packed, or profound, and yet I think that it might have had all that if there was maybe just another rewrite or better directing or something that could have put it all together better. After watching it I kind of wanted to like it, but just.... Anyway, here's the IMDB link maybe you'll see that special something clearer than me.
