I've always been annoyed by stuff I can pick holes in, like Dr Who, Star Wars, Matrix. Dr Who even more so, because of the sets that are always a bit rubbish/cheap. However, the latest Dr who, bespite all the usual script issues as pointed out above, I've enjoyed. I'm not sure if it's because I like looking at Amy Pond, or I don't give a toss anymore.
I still look back at Tom Baker times fondly, but I expect they were just as rubbish, even more so probably, but I was too young to pick holes in the script or scowl at the shonky sets.
They're producing everything to a small budget I expect and within time scales. The ideas have been pretty good this season, school boy stuff with some eye candy and titilation for the Dads.
