You mention:

"it’s called 'the power of understanding' in the book, but changing it to 'self-respect' is infinitely more insightful."

In defense of the original, there's good reason for it to be called "understanding" in the comic. Scott has a VERY different arc in the comics and the circumstances in which he gains the final upgrade is quite different as well. Without spoiling too much, Scott's ability to empathize with others--and with one person in particular--is instrumental to the climax of the story. I won't spoil it beyond that, but I think "understanding" is perfect for the comic and "self respect" is perfect for the movie. Perhaps you'll agree when you get there.

Also, I think you're being unduly harsh on Nussbaum. I love the movie and I think some of her points are way off, but I think she also raises some interesting issues. The movie is slightly problematic, I just don't think it's as problematic as she insists.
