In my mind, most importantly, the original ends with Neo back from the dead, having healed himself from several gunshot wounds. He then fights off three agents effortlessly and destroys Smith. It's clear he's now omnipotent within the Matrix - he's freed his mind and is no longer constrained by the rules of the Matrix.
The sequels downgrade him to "quite strong, quite quick, flies". They seem to backtrack for the sake of spinning things out.
