- Much <3 for Kate Stewart.
- Amy and Rory need to decide whether they're in or out. They are as annoying as a cat that's always on the wrong side of the door.
- The Cubes reminded me rather of the plastic daffodils from Terror of the Autons, which also remained inert until millions had welcomed them into their homes.
- See also Trillions by Nicholas Fisk, in which weird tiny crystals inexplicably arrive on Earth overnight.
Overall? Enjoyed it apart from the anticlimactic ending and the kissing, OH GOD THE ENDLESS KISSING.
