SG-1 had two big moments when it jumped the shark - points of no return: the destruction of Tollana (nonsense) in season 5 and this.
You can't simply have a CSG with 5000 sailors destroyed in the Pacific and cover it up. You can't cover up a full blown space invasion. This worked with the 2 Hattacks in season 1 but this was a full blown invasion. Simply doesn't work. The series should have ended there. The last 6 or so episodes of season 8 are great but the rest is simply... it jumped the shark hard.
Also, the replicators should have remained in the time bubble from season 6.
The asgard using the beam transporter to manufacture devices has been an obvious point that has finally been done here.
