Well okay, but you do realise your entire argument here is literally'I don't want any characters, creatures, or locations in this show to be explored in depth ever”…
Like, do you not understand how weird this argument is? Yeah I suppose the doctor needs to keep that air of mystery that surrounds himself, but I fail to see how what 'Listen' did was in any way insulting to the mystery of the show? What did we learn about the doctors past that we didn’t already know? That one day thousands of years ago he cried once in a barn?…because that’s literally it.
Did you get this angry when we first learnt the name of the doctor’s home planet in 'The Time Warrior'?
Did you get this angry when the doctor gave us an avid description of Gallifrey in 'Gridlock'?
Did you get this angry when we SAW Gallifrey on screen itself in 'The Sound of Drums'?
Did you get this angry when we learnt of the Time Lord Academy, or of the doctor’s childhood nickname of ‘Theta Sigma’, or of his friendship and education with the Master (Koschei) and the Rani (Ushas)?
We’ve known a great deal about the doctor’s back story and past right from the beginning, not least in Russell T Davies’ era of the show, so then why one earth would finding out that at one point in his childhood, the doctor cried himself to sleep, bother you? (oh wait, I know why…it’s called bias)
Look, with all due respect, this is a television show, With actual characters. Characters that deserve to have depth, to have exploration, to have their stories told. While, yes, the doctor is a mysterious character, there is no way that I want to have character exploration and development fridged for the sake of a principal. With your argument, you might as well not watch Doctor Who, or simply TV in general at all, because character development is always going to happen. Because it deserves to.
Getting pissed because Moffat showed us a few rooms in the TARDIS (even though we’ve seen the TARDIS interior many times before), or getting pissed because Moffat showed us the Time War, or getting pissed because Moffat showed us what a Dalek looks like on the inside seems simply nonsensical.These aspects of Doctor Who are huge and important world-building elements of the main character’s life. Why shouldn’t we see them?
Forgive Steven Moffat for daring to show us something quiet, and sincere. Forgive Steven Moffat for daring to show us something no writer has shown us before. Forgive Steven Moffat for showing us a meaningful and inspiring and important moment in the title character’s life.
Whether you liked it or not.
