I'm rather excited about a new storyline and characters.
Glad to hear it. The story arc during season 9 and 10 is pretty exciting. The show takes "epic" to a whole new level, you'll see!
Epic and ridiculous.
I remember liking the season 9 beginning and the end, but not the middle and found 10 to be "bleh".
Does Stargate Continuum take place after the other one? I don't remember it having a set place in a storyline. Honestly I rarely remember it. I just remember being disappointed by both movies. I had high hopes for the third that sounded good, but never made.
If buying the DVDs in the USA I suggest waiting until Thanksgiving, each season is always on sale for only $8 a piece.
