Season 5 is when I stopped watching the show entirely out of boredom, and I only finished it and season 6 in the weeks prior to the beginning of season 7. That's a hell of a gap. I stopped after part 1 of the weeping angels 2-parter, and I really liked Blink! This goes to show how weak early Moffat Who is.
I agree with you on Doctor's Wife, though I didn't remember that it was a season opener. It felt like a regular standalone episode (and a good one at that).
Season 7 though? Meh, besides the idea of a human turned Dalek I'm getting flashes of the time when I started to get burned out on the series during season 5. Episode 3 is only just beginning to foreshadow good stuff, and I hope I won't be disappointed.
