This week's was slightly better in that Gareth Roberts' scripts always make me laugh out loud and feel good about the universe. But really, I'm starting to consider setting up a kind of Sarah Jane Adventures version of Recyclingwatch:
THE SJA CHECKLIST
Crowds of people walking through London under alien influence: Big old check.
Tie-in with Doctor Who story: Semi-check. Nothing specific, but we do get a School Reunion flashback sequence.
Girl protagonist's mum is annoying: Check.
Mobile phone as plot device: Non-check, and a nice subversion of the way mobiles seem to be constantly used to break alien influence, in that this week a conveniently-timed mobile call to Clive fails to break his hypnosis.
Luke says something so daft that you have to wonder how he gets through life without being mercilessly bullied: Check. "She's a plant!" "You mean she's a vegetable lifeform?" (a fourteen-year-old boy who's never read or watched a spy story?)
Sonic lipstick: Non-check.
Wristwatch scanner: Check.
One or more of Sarah's companions falling under alien influence: Check.
