How big of a stickler are you for perfect video/audio quality?

I know this is a somewhat strange question on a Blu-ray forum. We all want the best that home video has to offer for video and audio quality in movies, but how much does it affect your viewing experience if a movie has moderate DNR, or doesn't have the latest lossless codec?

I've been noticing lately that several reviews of some of my favorite movies have relatively low marks for perceived video/audio quality, but while watching them it honestly just doesn't affect me..the movie itself is what is quality in my opinion, and owning it in the best possible format at the time is assurance enough for me. Do bad marks on quality in reviews dissuade you from buying or consistently watching movies that you like?
