10 Times Doctor Who Gave Fans EXACTLY What They Wanted

Now yes, we know we just said that the 60th anniversary could blow the 50th anniversary out of the water - and it very well might - but we couldn't give the top spot to something that hasn't happened yet, could we?

Just as he knew that Tom Baker's Curator would be an instant win with fans, Steven Moffat knew that bringing back David Tennant and linking him up with Matt Smith was the safest bet he could possibly make when crafting a multi-Doctor story to celebrate the show's half-century milestone - so that's exactly what he did.

With Tennant regularly topping "Best Doctor" polls, and the Smith era taking the show to international stardom, the Tenth and Eleventh Doctors had made the mighty Whovian army bigger than ever. So it's no surprise that they were top of fan wishlists when the 50th was looming, making it something of a no-brainer for Moffat to pick up the phone, and ask Tennant to return.

Though it was a tad disappointing that Christopher Eccleston couldn't complete the trifecta of NuWho Doctors, watching Tennant and Smith poke fun at each other's outfits, sonics, and Zygon-infused love lives was such a treat that any potential disappointment quickly faded away. And with 12.8 million viewers (making it one of the most popular modern episodes) and positive reviews all around, The Day of the Doctor was a huge success in every possible way.
