Don S. Davis has died, and with his passing, I feel like an essential part of Stargate SG-1 has gone missing. What is Stargate SG-1 without General Hammond? 
To be frank, when changes came to Stargate SG-1 in season seven, I missed Hammond more than I missed Jack at first. Maybe because his leaving was so abrupt, but Jack’s dragged out. By the time Jack became the General, it was a have-to case of him either moving on or ruining the show with his continued absences.
That’s not to say I didn’t miss Jack (Richard Dean Anderson) when he left, because I certainly did. But Hammond had always seemed like such an integral part of the series. I came to like Landry quite well after a while, but he was no Hammond.
I’ve posted news about Don Davis’s death for those who might want to know the details of Davis’s passing.
