I personally think this series has been a return to form, however it's still definitely not how it was or how it should be. I long for the days of RTD. At first Moffat felt like a breath of fresh air to me and I enjoyed series 5, the twists and turns and more 'intellectual' episodes really interested me, but then they just ran dry, however throughout the Ponds did remain good characters, as is Matt Smiths doctor. A comment that I read recently from Moffat was something about the new Whisper monster, and it went something along the lines of "we've brought the Cybermen and Ice Warriors back, so I thought we'd bring in a new monster". The whole point of Doctor Who is to have a monster every episode. Sure they do that, but not very effectively and in Moffat era Doctor Who, when is the monster ever the main focus? I miss the days when we had monsters like the Clockwork Robots, The Weeping Angels, The Slitheen, etc.The only Moffat era monster that has been memorable was the Silence and even they weren't used to their full potential, in my opinion.
All Moffat does is bring back old ones, and create boring, uninteresting ones that generally do nothing for the plot and are just there to fill the criteria. I miss those episodes where it was just the Doctor and his companion, and guests, being chased my monsters and saving the world. So maybe it wasn't 'intellectually stimulating' but it was a hell of a lot more fun, and frightening too. The scary episodes are always the best to me, and while they have come close, for example the episode two weeks ago with the ghost, the monster has just never been memorable or scary enough and it was only the atmosphere that did make it frightening. I feel Moffat is just trying too hard to make Doctor Who into something it shouldn't be. Yes, keep the twists and turns all you like, they are interesting, but for god sake, please start making some memorable monsters and just let the episode be about that, and that only, for once.
