One of the nice parts of previous seasons of the new Doctor Who were the associated commentaries available to download (as a podcast). I use to listen to them a day or two after watching the episode and get a real insight into how the episode was made. It certainly explained the effort, skill and work put into the series by the Doctor Who team.
With the new season of Doctor Who, there doesn’t appear to be any commentaries, that’s a pity.
Think everythings covered in the Confidential which is on BBC3 STRAIGHT after the episode, they’re as long as the episode now!
We’ve always had Confidential and as originally broadcast it has always been 45 minutes. Only the repeat is a shortened 15 minute version. The commentaries were different, akin to those on DVDs and meant to be listened to as you watched the actual episode.
