I've watched two episodes so far on 2 HDTVs, and honestly, I'm impressed. The external shots that I've seen so far look pretty great, maybe I just don't have the eye (or the TV!) that some of you do. The picture looks great on both "Time Squared" and "Unnatural Selection," especially the live-action shots, but also the special effects.
I'm looking forward to watching more from the set, and also the special features--which were awesome on the season 1 set.
And, I have to say, that Season 3 trailer...*drool*
