There were complaints about the freaking Borg corpse in "Blood Fever". I don't know why, but folks were just ready to tear into the show for the most minor things.
That and the other episode that had the escaped Borg (I'm not too familiar with Voyager, I think they were at the end of season 3) were good lead-ins to Scorpion IMO. Spooky mysteries, which is how the Borg should be.
I would never "tear into the show" but there seemed to be some excellent episodes (the surviving dinosaurs, the Borg episodes I mentioned, Timeless
, Living Witness
, Blink Of An Eye
) surrounded by alot of crap.
