Thank you, David Tennant

It's the end, but the moment has been prepared for.

It's certainly been trailered like nobody's business.

In about 26 hours time, Matt Smith will take on the most iconic role in British science fiction and David Tennant will join an elite club of former Doctors.

Before 2005 and the revival, I'd never really heard of David Tennant. When he was cast as the Doctor, I was willing to give him a chance and I was also willing to give the costume a chance.

From his initial appearances, it appeared that this Doctor was going to be a "Cockney wideboy in space".

But Tennant provided so much more than that. His Doctor was truly multi-faceted and varied. From the manic motormouth, to the lonely god, to the voice of time itself, to the oncoming storm that proved so terrible to the Family of Blood, Tennant played them all brilliantly. He (and his expressive face) was always enthralling and it must be said that the only poor episode of his reign hardly had him in.

Mr. Tennant's charisma and sheer talent kept the show strong and made it stronger. A hugely recognisable man, he will personify the Doctor for many of the young generation. Matt Smith has some big Converse All-Stars to fill.

I would like to say, from the bottom of my heart, thank you, Mr. Tennant. You are simply the best of the Doctors.
