I still disagree too - I don't really think that the time at which the show airs is a proper argument as to where the content is going. Also, the air-time isn't a constant either, as it changes from region to region, country to country. Here where I live, you might be lucky enough to catch an episode an hour from now - That would be three in the morning.
I don't think they've ever tried to 'go over the heads of the little kids' because I genuinely don't believe that the show was ever intentionally targeted at said kids. I'm sorry, Hannah Montana is a kids show, this just isn't. You can't really compare Doctor Who and it's content reliably to any
proper 'kids' shows that have been on in the last decade or so, from the relaunch of Doctor Who and up until now. The directors in the 60s even explicitly stated that it was meant to be an educational 'family' show. And there's really no arguing that 'family' means 'kids'. All kids shows are family shows - You aren't going to scare or confuse an adult with a squirrel telling badly synced one-liners, but not all family shows are kids shows, and not all families necessarily include tweens or lower.
The moment that a show repeatedly crosses the lines of themes and elements suitable for children to watch and comprehend, it's not really a kids show anymore, and that's yet another reason why I think your argument that the show is primarily targeted at children falls short. If it was, then every episode would be, not some
of them, not even most
. You don't get that one episode of Spongebob that's full of sex-jokes either. (Bad example, considering that Spongebob is full
of adult material, bordering on what I'd dare call a kids show to begin with.)
I think the show has always been targeted mostly at adults, I think you can express adult themes without going overboard and having to spray the inner workings of other people all over the camera and wiggle your tits about. (I say 'your' here in reference to you avatar. As much as I'd love it if she did, it's not necessary.
I don't see what you mean when you say that it would emphasize it more than it does - Just look at tonight's episode.
Also - Yes, if the writer says that what it means, then that is
what it means. Your own interpretation sort of becomes invalid when the creator of something tells you what it's purpose is, whether it's a vacuum cleaner or a book. If Tolkien had told us that 'Sting' was actually a trolls penis, then that's what it would've been. Whether it was said in the episode itself, or outside, that's completely irrelevant - The author said it.
