Well, just because I don't wanna see this thread closed and I like Dr. Who (despite I only watched the new series), these are my thoughts:
About the series in general:
It's OK. It have good stories and good characters, just simply the fact the Tardis is a practical and compact time machine bigger on the inside tells you how good are mixed the sci-fi and the creativity and imagination in the show. Of course there some episodes that are not so good and the show have their faults, but for me It's a good TV show.
It's a shame this series is barely known in Latin America, where I from I never heard about the Doctor, his companions, the Daleks and the stories around it. Was until 2011-2012 when I started to watch the new series and oh boy oh boy, was one of my best decisions I ever made. But I definitely doubt to see Dr. Who (dubbed or with subtitles) in the TV of my country, but that's why there is the Internet!
About the 50 anniversary special:
HOLY SHET GUYS!
THAT SCENE WITH THE PREVIOUS DOCTORS AT THE END-waitwaitwait, calm down buddy.
Was great to see Tennant again as the Doctor, show good chemistry with Smith and Hurt. When John Hurt was annunciated as the "8.5 Doctor" I don't know why many people complaint about it, for me he made a good job as the Doctor who did the impossible on the Time War. Also, was good the cameo of Eccleston and the scene in the museum with Tom Baker was good too (which start me wondering how was his role as the 4th Doctor).
About Rory:
I believe the reason why many people dislike him is because the people see him as a filler character, just think about it, what was the main focus of the 5th and 6th series of Doctor Who?: Amy Pond, the Silence, the confusing plot "oh my god I can believe it! I gonna marry with my semi-daughter" of River Song, and in addition he always had the mark of the death, that probably don't help to build a good character, and don't get me wrong, I like Rory but yeah…
(plus, that son of bitch was married with a pretty redhead)
