Yeah, I'm fed up with the use of the sonic screwdriver. Especially in the rings or akendendom or whatever. It's just the writer lacking creativity and getting the doctor and co out of any situation by using it. I remember in some Tennant episodes he said it couldn't work against wood, yet the doctor can do pretty much anything else with it. bad writing, although this serie has been a big imrovement over the travesty that was series 6, the writing has become sloppy in alot of cases.
