Stargate fans pretty much disgraced themselves with their insane backlash over Stargate: Universe, where they demonstrated raw and unbridled hate for the first Stargate series that wasn't a saturday morning cartoon. Fans went beyond the pale with not merely legitimate criticisms, but essentially refusing to comprehend what they were seeing on the screen. (People talking? Character development? What's that? WHY NO BODY SHOOT ALIENS THIS WEEK?)
Bonus: an irony with citing these two shows together is that insanely bitter Stargaters cried that SGU was just a clone of BSG where everyone was depressed, angry, etc etc all the time. It was a convenient excuse, since compared to NuBSG, SGU was Foster's Home For Imaginary Friends.
