Compared to Continuum, this is just plain pants.
This plays much more like an elongated SG1 episode, rather than a feature, it looks like it too, very "TV" and for the most part...dull.
It's lightened up only by (again) Ben Browder and, the chemistry between him and Amanda Tapping's Lt. Col. Carter.
You also need to know more of the back story, as explained in prior episodes, to fully appreciate the plot in this one. Didn't enjoy it as much as Continuum.
