There's an early review of the season 2 DVD set -- or, rather, the first disc (since the reviewer was only sent the first and fourth discs) at http://www.hometheaterforum.com/htforum/showthread.php?s=&threadid=163899 , with some screenshots to whet our appetites.
Doesn't look like Fox went as all-out on this one as they did on the first (I was hoping for more of those cute little character introductions), but then, the first set didn't sell at FAMILY GUY or FUTURAMA levels, let alone THE SIMPSONS. (KotH is more popular than FAMILY GUY with a broader audience, but not with the DVD-buying demographic, I guess.) Just as long as they keep releasing the seasons, I'll be happy, but let's all buy the set ASAP to help make sure that we get more seasons.
