Query: Good season marred by DVD mishap

I won't go into detail about this season as many other reviewers have written wonderful synopsis of the episodes, but I will say this: a potentially five star season DVD has been reduced to two because it is simply not complete nor up to the quality of the season seven and six sets. 'Threads' is the shorter syndicated version of the episode and there is no commentary on it either.I'm sorry for giving this such a low rating, but MGM/Sony needs to get their DVD releases together,
