As someone who can think outside of the box, and hang with most plots, I am left with four thoughts:
1. Excellent visual and sensory stimulation.
2. What the hell did I just watch?
3. That's 2 1/2 hours of my life that I will never get back, (unless I can become "inverted")
4. I've finally watched a movie that I cannot explain to others except for the weak one sentence that says "a guy tries to save the world from WWIII."
