Martha was fucking great. To me she seemed to have been the only new Companion who really did some things on her own. She acted on her feelings for the doctor, she walked the earth for a full year, telling everybody about him, during the Utopia arc, and I still consider her to be my favourite Doctor Who companion.
About the link: I don't really like Moffat's style, loved David Tennant, didn't really like Matt Smith, and look forward to Capaldi.
