I disagree. I watched it today, and I think it might take the place as my favorite episode. I felt that every element in it made sense and played an important role (with the possible exception of the Moment manifesting as Bad Wolf Rose), and it explored aspects of the Doctor's character which had never been explored adequately before. It was the best-paced episode I've watched; less frantic than a lot of new series episodes, but at the same time far less plodding than most of the original series episodes. Then again, I haven't watched everything in Doctor Who, and my opinions on what I have watched are far from typical: I actually preferred A Time of Angels and Flesh and Stone to Blink, in no small part due to those episodes revolving around the Doctor and others in the core cast instead of new characters that they didn't give me adequate reason to care about.

I also disagree, but not quite as fervently. I felt it was a superb episode, and on its own made sense and was a great relief compared to the latest episodes. That said, it seems to conflict with certain other episodes and I honestly thought gallifrey was already frozen in time rather than burning forever...?

It does not rank anywhere near my favourite episode, but it is a highlight of the show as a whole, definitely. Also I love Clara and I think she's becoming the best companion since Martha at least, as long as she doesn't get screwed over in series 8.
