I liked Season 2 too. The finale was a bit dull but like Ray said it had some good episodes.

Nice seeing some Donna love here and there. My guess is that storyline is pretty much done. She's married and happy. While I liked the character I'm ok if they left her alone. It would be nice though if she got her memories back without her brain blowing though.

Some characters I would like to really see them revisit is Susan and Roman. I recently watched the end of the original episode where Susan and the doctor parted company. Now it looks like she and Romana ended back on doomed Gallifry but I still hope there's more to their story.

Fair play!
