I wasn't expecting a mid-season cliffhanger. Good one. The rest of the episode was pretty good too and the reasoning they're using to justify all the build-up surrounding the chair works for me.
Three more things...
- I didn't like how modern-day computers were compatible with ancient tech, but when I think about it, I guess they've had time to research this stuff during the SG-1/Atlantis period and build some compatibility.
- This show has a real ensemble cast.
- Looks like Ming Na was bumped back up to main cast member from guest status.
When is the show coming back? I imagine it'll be months from now, sometime in the spring.
