You can't watch an intentionally bleak video (though a brilliant one) that takes things out of context, and a few snippets from another episode, and judge a character. You could do the same thing with nine and he wouldn't look all that wonderful either. (btw, it was nine that left jack on satellite five, knowing he was alive, because he felt "wrong".)
at least check out the first couple episodes with ten - the christmas invasion and "new earth". If you still don't like ten, well at least you'll know you gave it a try. Cause boy he's wonderful - he's been best described as "complex" - he's kind, compassionate, heroic, manic and friendly. He can also be ruthless when you cross him. And rude. and those 3 seasons with him had some great moments.
Anyway, even if you decide not to give him a try, at least check out "blink" from the 3rd season. A great episode that was voted as one of the top tep episodes of all time - and it only has a few brief cameos from ten. So even if you don't like him you'll probably enjoy it.
