How did I not know this was here before? I absolutely must join.

Favorite Doctor: Out of the original airings I would say Tom Baker [4th doctor] was my favorite, that was until the newer airings where I fell in love with David Tennant. I think Tennant bought an emotion to the doctor that we hadn't seen before, the 'angry / chaotic / in pain' doctor, seen in episodes like 'the runaway bride' or the 'family of blood' [He pushes Mother of Mine out of the TARDIS into the event horizon of a collapsing galaxy, wraps Father of Mine in unbreakable chains forged in the heart of a dwarf star, traps Sister of Mine in every mirror in existence, and suspends Son of Mine as a scarecrow.]
Favorite Companion: I enjoyed Amy as a companion, once Rory because more of an integral part. The two had a good chemistry and they seemed more actual friends to the doctor than companions at points.
