Since Atlantis started, I have been watching both series by following the watch guide on the gateworld website.
While seasons 9 and 10 of SG-1 were OK, they were not nearly as interesting as Atlanis was, so I found myself looking forward to finishing SG-1.
Now, that it is over, I am a bit relieved and in future rewatches, I will likely skip seasons 9 and 10.
Atlantis has been great the whole way though. I really like the cast, but I just saw that Weir was replaced and I am surprised about that decision as I thought she played that role really well.
I am still early in season 4 of Atlantis, but I will likely get through it quickly as I put the show on any chance I get.
I did watch the ark of truth movie and did not like that at all. I look forward to the next movie, which I believe I am supposed to watch at the end of season 4 of Atlantis.
Atlantis is awesome, the only letdown for me was the ending. I believe the intention was to do one or two movies just like they did with SG-1 to wrap everything up. But it fell through and so we were left hanging.
