Funny enough I'm going through NuWho and re-watching them at the moment, so I'll hopefully have a clearer perspective on Moffat after that (although I don't have Series 6-10 minus Day of the Doctor on DVD, so I'll either need to shell out for that or call it a day). From memory though, Series 5 was meh, nowhere near as good as the RTD era but still somewhat competent in places I guess? Series 6 was a definite low point, and from memory easily the worst NuWho series of all and possibly the worst series in all Doctor Who, certainly a contender anyway. Series 7, part 1 anyway was still fairly bad, to my mind especially by part 2 things picked up a tiny but, but seeing as it came straight after series 6 anything would look like an improvement. Day of the Doctor up until that point was the highlight of the Moffat era and probably stands as the Smith era's best piece (mostly due to the other two Doctors though), and Time of the Doctor managed to bitterly disappoint once again. Series 8 was a stark improvement, actually began to enjoy the show again as opposed to moaning about everything in it constantly. Series 9 whilst having some good moments also had some worse moments than series 8, I guess it was less consistent generally, mostly due to the lows lasting longer thanks to them being mostly two-parters but the highs also lasting longer due to that. Overall another okay one, I struggle to decide where it stands compared with series 8 though. Characterization was better in 8 I guess... Series 10 meanwhile is almost certainly the Moffat-Era's highlight, he went out on a bang I reckon. One of my favourite series to memory, if nothing else definitely the best Moffat series (re-watching series 2 which was previously my least favourite RTD series, that being better than I remembered it puts how high series 10 ranks with me in jeopardy, we'll have to see where everything lies after I finish). So yeah in conclusion, started off meh to okay in hindsight with 5 (will need to seriously watch and re-evaluate), went extremely downhill in series 6, plodded along mostly for series 7, picked up in series 8 and reached its high point in series 10. That year break Moff took from Doctor Who seems to have really paid off.
