^ I like Confidential. I think it's pretty in-depth naman. You basically get a look at how the episode was made, preprod to postprod - from the point of view of key people: the producers, director, writer, actors, production managers, technical directors, animators, etc.
So, if there's a particular episode that you enjoyed, or if it's written or directed by someone you respect, you're sure to get some great insights from the connected Confidential
. I really enjoy it because the 3 Doctor Who leads have such excellent chemistry, it's fun to watch them goof off.
