The Tenth Doctor in "Planet of the Dead"

David Tennant has done great things with The tenth Doctor and it was very very hard to see him leave.
I am going to state several things that jumped out at me when David was the doctor.
1: He always made up the funniest words that made him enjoyable to watch.
2: He almost always had a smile on his face.
3: His hair was the best.
4: He has made me laugh cry and have many mixed emotions.

he is the best doctor and always will be.
