Crowds of people walking through London under alien influence: No. Still thinking the casting department's had a budget cut.
Tie-in with Doctor Who story: Well, it technically is a Doctor Who story, seeing as Doctor Who is in it, so yes.
Rani's Mum is annoying: Wouldn't you just know she'd be the sort to tell embarrassing stories about her honeymoon at other people's weddings? It's a wonder Rani's Dad hasn't sued for divorce.
Star Wars reference: Unless the title is an oblique reference to the novel The Courtship of Princess Leia, no.
Mobile phone as plot device: No, though a GPS does figure in episode one.
Luke says something so daft that you have to wonder how he gets through life without being mercilessly bullied: “What do I call him? Dad?” Since it's Sarah and Peter's third date and he hasn't proposed yet, methinks he's jumping the gun a little.
K9 interprets a figurative English expression literally: Check-- practically every second line.
Sonic lipstick: Check. Had Sarah succeeded in blowing her own head off with it in episode one, we might have been spared Episode 2.
Wristwatch scanner: Sarah removes it as some metaphor for how she's so utterly sick of the lifestyle which she tells us is completely wonderful twice a season. I think she might have issues.
One or more of Sarah's companions falling under alien influence: Yes, kind of-- Sarah winds up under mind control via an enchanted engagement ring for a bit, but seriously, with Sarah deciding to chuck in her lifestyle every time some relative/boyfriend turns up (was this just “The Temptation of Sarah Jane” in reverse, or what?), who needs mind control?
Sarah and/or companions acts like a selfish cow: Apparently meeting Mr Right means you have to give up all your previous mates and everything you enjoy doing, and she winds up telling Mr Right to go kill himself, literally, when she realises this. I really think she's got issues.
Over on Dollhouse, Michael Hogan guested this week. I think the series is secretly set on Caprica.
