One of the things I didn't like about the movie was it completely failed to show SE and SS as having any kind of bond. The movie portrayed them as enemies from their first meeting all the way through. It was so one dimensional. Basically SE was good and SS was bad, so when the end came there was no real tension regarding their relationship. Two old friends facing eachother on the opposite sides. This is one of the aspects of their relationship that was consistent through all continuities and they dropped it in the movie.
In the movie, if I recall correctly, you see SE sort of look at SS fall almost like SE has some regret, but it's completely useless since SS is purely portrayed as a jerk through the whole film. Just one of the failures of the movie in my opinion.
