i've only just got around to watching this. i was a fan of the earlier series, The Untold Story of Stewie Griffin was great, and Blue Harvest was ok, but this season was pretty lame, except for the Stewie Kills Lois and Lois Kills Stewie episodes. I haven't watch the last few yet, and i'm hoping the stand will pick up a bit.
EDIT: the last disc just had the inevitable 'special' <yawn> features', so i HAVE watched them all. Not impressed.
