Query: Great comparison of the two Doctors

With all the deserved hoopla over David Tennant as the 10th Doctor, people forget that when Dr. Who reemerged with Chris Eccleston as the 9th Doctor there was an equal amount of hoopla. Now he's overlooked. So buying these two years together, year one with Eccleston and year two with Tennant, bound together with Rose as the companion offer a good comparison. I never want to forget Eccleston's perormance. Had he continued, the series would have been every bit as good, albeit in a different direction. He is the least quirky, or most "normal" of all the Doctors I am familiar with and that leant a level of believability to the character. He's almost the "superhero space alien next door". Kind, caring, and an ironic sense of humor, somewhat distant and mysterious with none of Tennant's manic qualities
