You mean the technology isn't real? Unlike other movies from which influences were drawn, there was no exposition and Nolan's "interpretation" of dream world was severely lacking. What was the point of the snow base at the end? None really. I think the biggest problem I had was outside of Cobb's story, people weren't fleshed out. Ellen Page just gets pulled aside and all of a sudden she's a "dream architect" and she didn't even know what was happening 30 seconds earlier. Half of the reviews and opinions of the movie was that it is extremely convoluted, and unlike Shutter Island which was able to explain every frame away, this was more of a experience than a story. I guess I just tried to make sense of what was happening.
