See, now THAT annoys me twice as much as complete series sets for long-running series do in general: I hate when these studios begin releasing individual season sets of a certain show, then after they release like two seasons or so, they're like screw it, let's just release the complete series and be done with it. That's sto STUPID!
They did the same thing with LEAVE IT TO BEAVER years ago: they released the first two seasons individual, then after a period of no new releases, Universal decided to just release the complete series instead, which makes me so mad.
I've said it before, but I'll keep saying it until the cows come home: COMPLETE SERIES SETS ARE MORE LOGICAL FOR SHORT-RUNNER SERIES THAT LASTED ONLY A SEASON OR TWO AT BEST!
