I didn't mind seeing Luke too much until he started eyebrowing again. Also, I noticed he doesn't seem to blink.
Well, maybe no real Clyni action, but it's pretty obvious what Clyde wanted to tell her on his phone message before he passed out.
It was a reasonable finale, anyway. Thingy from Survivors was a good choice for a younger, better, stronger Sarah Jane and I liked the bit where Rani was crying and her mum said she was jealous sometimes. Of course, every finale has to end with a slightly patronising "aliens won't stop trying to destroy the earth, but we'll always be here to defend it" thing, followed by a shot of the planet.
