While not the noblest Romana of them all, and even that I personally liked Romana II better.. I did appreciate how Tamm played the role (was written) much closer to an equal of the Doctor, as opposed to Lalla Ward's version that generally came off as more of a companion/assistant.
Can't say I know her from anything else, but her Romana was a formidable woman.
I just finished watching the Key to time the other day. Last night or the night before Lise and I were talking about Lalla Ward and how weird it was the she was Astrid in the Key to time, and then Romana afterwards.
Not to threadjack, but did you know that Lalla Ward married Tom Baker, and then after divorcing him, later married Richard Dawkins?
It's got a cushy Monday-night timeslot, so even if it stinks (which by most reviews, it does), it could still make it all season. I was going to watch it last night before RAW, but got hooked onto a CSI episode on Spike TV.
