I too like both Tenant and Smith. Eccleston was good too and I was a bit upset when they first brought Tenant on, but I soon grew to like him even more than Eccleston.
Donna and Aimi are my favorite companions. Donna was just so different from any other companion...lol.
I like the cat people, tree people, the ood, and the weeping angels. One of my favorite scenes is the end of the world episode with Rose when they play the 'traditional ballad' Britney Spears 'Toxic'...couldn't stop laughing when I first saw that one.
