I do think that some of the media reports are biased or making mountains out of mole hills. I'm not worried. These demos they are reviewing are already months old, so whatever they are polishing right now is already ahead of what the reviews are based on.
We all have different feelings on these issues, including the people who wrote the reviews.
No game will be free of glitches or bugs, but hopefully by release they will be minor and few and far between.
