Finally!
Yes, the 13th Doctor has a certain talent for building things. She's got more experience than any of the other Doctors had, of course she's going to be more resourceful!
I really liked the bit where they told her she was a woman and all they got was a casually excited "Am I?! Does it suit me?" I think she would've reacted the same way if she'd regenerated as a ginger-haired man. Also: "I never go anywhere that's just initials" was an awesome line. Is that new, or has one of the other Doctors said that before?
I'm not sure how much she'll be like any other Doctor, but in this episode I got a general Eccleston-Tennant vibe. The bit at the end where she gave the alien (can't remember his name just now) a second chance and tried to talk things out with him, while having a deadly trap set for him in case he wouldn't listen to reason, reminded me of Tennant's first episode-- "No second chances." Not nearly that ruthless, but the scene had that sort of flavor to it. She did give him the thing he needed to get back home, so I wouldn't say she's QUITE as vicious as that.
What does everyone think of the new companions? I haven't formed a full opinion on them just yet, but I'm glad they've got more than one of them again. Assuming they write the characters well, that should give the show room for more depth.
