Doctor Who: Every Regeneration Ranked From Worst To Best

Dying as a result of radiation poisoning while rescuing Wilfred Mott, the Tenth Doctor embarks on one last tour of the universe to say goodbye to those he loves.

Captain Jack, Martha, Donna, and even Rose all get their final moments with the Doctor, before he enters the TARDIS one last time.

Slowly pacing around his trusty ship, the Doctor's face runs the full gamut of emotions from fear to anger, regret to sadness. As he realises his time has come, he stares almost directly down the camera, in the eyes of everyone watching, and says "I don't want to go."

Tennant's Doctor then explodes in a burst of light, destroying his version of the TARDIS in the process.

It's heartbreaking, plain and simple. Eccleston might have started the Who revival, but it was David Tennant that made the show a household staple. His version of the Doctor is one of the best of all time, and there wasn't a dry eye across the country when he said goodbye.

Without Tennant, Doctor Who would not be the show it is today. It's only appropriate that he got the grandest sendoff in the history of the programme.
