Okay, so the Goa'uld are finally defeated, along with the Replicators, and the Jaffa have gained their freedom, bringing the Milky Way into a state of peace, or as our heroes find out, not a long-lasting one as an offshot group of the Ancients (The Gatebuilders), ascended and forcing many into a religious cult or else they will die, and they are called the Ori, the deadliest foes yet.
Richard Dean Anderson sadly retired from the series as a main character, and he is replaced by Ben Browder of Farscape fame, those hearing about this now and worrying about it, don't, as Ben is a talented actor and you quickly care for his character, Cameron Mitchell. Another temporary shock is that Amanda Tapping is absent in the first few eps of this season (Due to having a child), but her boots are filled in by ANOTHER Farscape veteran, Claudia Black.
Not to worry, this show does not become 'Fargate', it still shares the same quality writing, as a whole new can of worms is opened up for writers to use, and even new writers come in, such as Alan Macolough who writes several eps, all of which are highly memorable. But not a single bad or boring episode is in sight.
Extras are plenty too, with commentaries brimming along with behind the scenes footage for fans to enjoy, so please do as another season of pure Stargate goodness is in your hands.
