Well hearing someone say "Davies/Tennant was the peak..." kinda... well, er, using British terms, rustles my jimmies? I am a huge Moffat supporter and I am of the opinion that the show only went uphill when he took over as showrunner, having loved every season finale more than any of RTD's (save for The Wedding of River Song, it was a bit lackluster in some regards.) But S7 and S5 are my favorite seasons of Doctor Who EVER, so it saddens me to see people not enjoying them wholeheartedly. Lots of people are highly critical of Moffat but there's an equal number (or probably a great number if you take into account casual viewers and Tumblr fangirls) that just absolutely adore what he's done. While I can critique what he's done a good bit, I still enjoy his take on the show way more than RTD's soap opera drama version of Doctor Who. I could sit here and criticize Rose and the decisions he made with Rose for hours on end, or go into depth about how almost all of RTD's finales had a fantastic setup (mainly Utopia, The Stolen Earth, and the first part of the End of Time) only to be absolutely dreadful in the end (Rose's happy sappy ending with the Meta-Ten, the Master's lightning powers, the Doctor being aged into gollum-old-man, the Doctor being resurrected a la religious parallels, the list goes on.) While neither showrunner is perfect and their eras have had significant ups and downs, I find Moffat on the whole to have a better handle on the show, being more akin to how Classic Who was written and capturing the feel a bit better, while also incorporating time travel as a plot element rather than just a means of traveling, and having really complex and highly interesting stories. While he has many flaws, I just really enjoy his take on the show and feel that the show has been on a significant uphill stride ever since Series 7B. With that series, the 50th, The Night of the Doctor, and the Time of the Doctor on the way, I'm of the opinion that the show's writing, feeling, and overall scope has been captured almost perfectly and with the arrival of a new Doctor and the return of Gallifrey, the show can only continue improving.
ariich, I believe, is of the exact same opinion, so I'm surprised he hasn't popped in with a big sad face too. Hopefully you'll like the rest of the season, though-- The Name of the Doctor into The Day of the Doctor has been one of the best 1-2's the show has given us, so maybe that'll change your opinion, too.
In other news, I've been watching Tom Baker's era a good bit recently and I just love it. Definitely my second or third favorite Doctor.
