Hammond was great and Don S. Davis did a great job portraying him. He was definitely the guy in charge of the base, and he was never a character who was there to cause neverending conflict with the main guys nor was he the character who just sat there, enabled them, and let them run amok. I loved O'Neill, but his season as The Man was a bit of joke. If they had used Jack as more than a non-stop pun maker, he might have worked better that season.
