I'm loving Britt and Jason. It's nice to see Jason smile and Burton actually seems engaged. Steve and Kelly T. have great chemistry. Britt has personality and a pulse. Carly needs to quit being a cockblocker, lol. I wished she had walked in on them actually kissing because I want to see her head explode.
What I don't love is the ridiculous propping of Jason (and Carly). Liz has to apologize to Carly for thinking Jason killed Franco? What? Then Liz has to thank Carly for standing by Jason, and go on and on about how amazing their friendship is? WTF? I don't mind seeing Liz and Carly
Jackie Lane never had much of a chance as Dodo, and the character was treated poorly in her exit as well as future (non-canonical) novel material. I can't blame Jackie for not wanting to have much to do with Doctor Who, but I'm glad she participated in the 50th anniversary.
