Finally nabbed it on DVD and started watching it. This show is spy/sci fi geek GOLD!!!! I love it. And I must say, "Chuck vs the Wookie" is my favorite ep so far. Yvonne Strahovsy and Mini Anden kicking ass in skimpy outfits? Oh my.
I'd probably never even seen her before I watched this ep. I spent last night downloading pictures of her. Blue-eyed redheads!
They generally kept it fun. And some eps were as you said, comedy gold. But all of it was fun, generally. Occasionally they slipped into taking themselves seriously, WTF?!, but thankfully soon they'd get back to their basics, or at least the reason I watched it so frequently (online, mostly, I must admit)- geeky fun, bit of camp, hot chicks, light hearted most of time.
Saw the one where he gets out of a jam because he and his old buddy plan a tactic speaking openly in front of the bad guy - in Klingonese.
