"The Moth" is crucial because, while it may be heavy-handed, it also sets out a lot of the thematic material of the show, particularly Locke's philosophy, in no uncertain terms. Things like clinging to obsessions, the importance of struggle, and salvation are foregrounded in a way that signposts them as being…

"Can someone help me with why Locke punches Charlie?"

I do actually remember the Doctor saying "2016" at one point, but like I said, the sound mixing was so bad I couldn't tell what he was saying.

He is the last of his species. Gallifrey is in another universe entirely, and with the crack closed they're probably not coming back anytime soon.

Except for that psychic link that lets him sense the presence of other Time Lords, anywhere in space and time throughout the known universe.

You're worried about people empirically verifying somebody actually does have a mental issue before giving them medication?

"This episode of Doctor Who seemed to get behind the idea that the disembodied voices in your head that tell you to do things are your friends, and your friends, family, and doctors are trying to keep you from being special by asking you to take your meds and not to run off into a haunted forest by yourself to be…

With sound mixing this bad, the script probably isn't to blame in this case.

I seem to recall there were a few when the mom leaves her house.

Hell, the Dalek invasion at the end of series four was already erased from existence, so….the timey-wimey ball is on the court.

A lot of it has to do with the rise in next-gen video game consoles, I suspect. Now that people are constantly playing Halo at 60fps, of course they want all their action scenes running at a higher frame rate.

Apparently, this episode takes place in 2016, so maybe these are all the new kids.

If it was high up, that would probably help her get down quicker.

Except she wasn't mentally ill, which was the point: don't immediately jump to "give her pills" without at least looking for something which disproves the theory.

Doctor Who has never particularly shared that view of human nature. It's always gone back to the well of regular humans being timid and fearful reactionaries….except when they're smug and overbearing bullies with technology on their side, of course.

The first time I noticed it was "Mummy on the Orient Express", although I do have some dim memories of it during the Tennant era, maybe series three-ish.

I wouldn't even call it a trope. More like a fundamental philosophical issue. After all, many religious experiences can seem like schizophrenic episodes, and vice versa.

I quite liked the pastoral quality of this episode. It's the "As You Like It" of series eight.

Except for "The Day of the Doctor" and "The Time of the Doctor", which expertly tied together the seven previous years' worth of storytelling with a neat little bow on top.

To be honest, I keep forgetting it was retitled for America, given how many times they ominously drop the name in the early episodes.
