He had a friend in every port. That's not just charisma. It would be impossible for him to have this attitude and gain command in the prime universe. Without saving Earth, he probably ends up suspended for the Kobiashi Maru in NuTrek. Unless Starfleet is as reckless as he is, I don't see him just doing what he wants. In the series, he debated whether or not to do something against the rules. In the movies, no debate. He just does what he wants. He gets the Enterprise in TMP, he takes the Enterprise in III, he goes to see God in TFF, and he scolds Spock for asking him to be apart of the peace mission--brooding, drinking Romulan Ale, snipping at Spock (I hope you're happy), and telling his personal log he can't get past the death of his son. This is a case of arrogance that would've gotten him snapped back. His reputation is the only way he could get away with it in the movies. He doesn't have that reputation in TOS.
