I've noticed that all three of the new DOCTOR WHO series tend to gain momentum as they go along, and the summer evenings get longer and longer. My reactions tend to change from "is that it?" to "ah, I see where they're going with this". And all it takes is three good episodes in a row, and all seems right with the world. BLINK was a script that had it all - dialogue to die for, proper scares, humour, intelligence beaming out of its chuff.
And last night's epilogue? Great work trying to make an entire generation of kids afraid of statues, Mr Moffat. You rotter.
