People were not just critisizing it just for Peter Kay, read all the OG comments, this episode was the worst yet, and if the Beeb has any sense, Russell T Davies will write less episodes next season, as for the running through the corrodor trick, thats lame, how many times have you seen it before? Thats just not Doctor Who. It's the Doctor who makes the show, you don;t just farm it out to a supporting cast.
On a good Note, Captain Jack will be back next series at least, he will appear at the start to console the Doctor
it will be good to see him, i have actually missed the character somewhat
