Wether u like this movie or not.... depends entirely on your perspective with which you watch it and also on the things you require for making the movie a hit for you .... which is quite different for everybody. I agree that the first half was a bit slow, but I took it as a neccessary build up for the actual plot of the movie cause the second half more than makes up for it. Some may say its inspired from the 'Moon' but since I haven't really watched that movie, Oblivion stands original and interesting enough for me.
