It was "over-hyped" because it was the first proper Dalek appearance on TV since 1989

And she's not scared because she knows she has the Doctor.

She pities the Dalek in "Dalek", due to not knowing what it's truly like. She hates them in the finale because they're all-out evil. Then she's not scared in "Doomsday" because she wiped them all out before and, this time, she has a Doctor to hand too.
