In alphabetical order:
Due South
Recently season 3 finally came out on dvd over here. I haven't even finished watching season 1 and 2, and even though they're quite enjoyable, I skipped right to season 3, because Callum Keith Rennie as Ray Kowalski; need I say more?! *lusts*
Firefly
My daughter is making me watch Firefly, because she kept on saying she thought I would really, really like it. So now we're watching it together. Why didn't anyone tell me just how awesome that series is?!?!? Oh right, a lot of people did, I just never listened...
Lost
They've started season 3 a couple of weeks ago over here; they've lost me. Pun intended because it's really not worth a better one.
Stargate Atlantis
I skipped the audio commentaries for season 2 that don't have David, Joe and/or Martin Gero in them, and went back to the audio commentaries for season 1 that do. My conclusion: Martin Gero is a god as far as I'm concerned, and I mean one of those nice ones, that actually do good with their divine abilities. My favorite moment is
when during 'The Siege, part 2' he interrupts Martin Wood to say "I love that line; 'So long Rodney'" (In Martin Wood's defense; I like how he points out every moment Rodney McKay gets to sit down or lean on something for a second, because he has to keep on going and going like a Duracell Bunny the rest of the time.)
Stargate: SG-1
We (youngest son, daughter and I) are still going slowly, because we absolutely want to watch this series together, and the logistics of that are complicated, but we're not in a hurry either, so we're fine with that. We are now in season 6 and have recently watched 'The Abyss': omgomgomgomgomgomgomgomgomgomgomgetc... In short: words fail. Seriously. So much love.
Supernatural
Erm... My daughter likes it, and when she's watching I try to watch with her, but I keep getting the urge to go fold laundry or something. We're now 3/4 into season 1 and I still don't see the attraction. Even Callum Keith Rennie was boring in it.
Torchwood
Finished the season.
I'm glad people persuaded me to keep watching, even after episode 6 'Countrycide' freaked me out; it's well worth it. I loved seeing more of Tosh whom I love very much, Jack got more sympathetic but he's still not my type, Gwen is lovely even if I want to smack some sense and sensibility into her sometimes, Rhys has a nice bum and boy do I crush on him because he's such a sweetheart, Owen keeps being creepy and even his love is selfish, and oh Ianto... I'd love to see more of him, even though part of the attraction is that he so quietly goes about his business, doing what needs to be done.
No surprise of course I bawled my eyes out for Gwen and Rhys in the season finale; Eve Myles acted my heart to pieces there.
