I've been finishing off a re-watch of S1 on DVD this week, and really enjoying it (just wish they'd given Diamond Phillips more time before... you know).
Sadly, I've barely cared about the show for the last couple of years. I'd actually never bothered to watch that S7 teaser until just now, but it doesn't do much for me. I mean, Kurtwood Smith is great and all, but otherwise, eh. Die Harder knock-off, and sullying the memory of Soulpatch. I'll watch via downloads and whatnot, but it has definitely lost its luster for me.
Also, I bought the PS2 game on the cheap recently, and I figure I'll play that at some point for the cutscenes. Anyone ever try it?
