Not necessarily bad and definitely not good either. Balanced on a precipice leaning towards flat out bad. Complaints run the gamut of blurry imaging in the widescreen versions of the episodes with white specks and other debris in the full frame versions. There has also been mention of the theme music being unusually slowed down in the "Galactica: 1980" episodes.
When, oh when will Universal Studios ever learn how to master the technology of the present day when it comes to releasing home media entertainment? They can't do it with Blu-Ray, they couldn't do it with DVD, and they couldn't do it with VHS.
It also hasn't helped matters any that Universal Studios hasn't been taking care of the original negatives of this series like they should have been doing during the past 37 years. And it shows in this Blu-Ray release, doesn't it?
Read the books Universal Studios has tried and failed to censor on Amazon.com...
And read these books at another location where Universal Studios executives and its stealth marketers won't be able to post negative, misleading (stealth marketed) reviews of the books via them purchasing candy and Rogaine Foam on Amazon.com (allowing them access to the Amazon book review section) and not actually buying and reading the books. I'll leave the other 150 global locations under wraps for now.
