I kinda liked the DTV follow ups. Not in the same league AT ALL, but fun little pictures that were at least given some decent production value and shot in widescreen (ahem...have we come on so far when we still get even more retarded s**t thrown at us like, um...Hollow Man 2?).
Besides, say if this set goes for $15 or even $20 online, you're basically getting the sequels "free". I just hope they move some of these special features to the sequel side - the movie has enough on its own with DTS, commentaries and the pilot, and its II and III that could do with having their image downgraded a few bits overall to fit those juicy extras in.
