Stokes' interpretation doesn't look deep enough. He attempts to figure out what is really happening before, after, or even during the movie. I find more use in interpretations that try and figure out what something means and what the underlying message the writer/director is making (if any).
Stokes focuses too much on plot and not enough on meaning. Reminds me of people who think the Six Sense is awesome (pretty much everyone) because of its amazing plot twist. But that's all it really had--not too much meaning. A movie worth analyzing shouldn't just stand on plot alone. Thankfully Inception has both an awesome plot and some decently profound meaning.
