Not wanting to sound too obvious, grade 3, but the BBC is currently three episodes into a new series.
I think the new Doctor is extremely good. Old time fans must remember the new series is being aimed at a. people who have never seen Who before in their lives and b. kids- after all, let no-omne ever fool themselves that Dr. Who was a show for adults. If you wanted that sci-fi effort aimed at adults, you wanted Blake's 7.
