A serialized hour of prime time family TV? There's never been a point.
And when there has, people have gone ape shit at the fact it's gotten confusing and "archy"
Who fans would be far happier accepting it's nonsense.
In the grand scheme of things, of course you're right; there is never a point. TV is pointless and we should all go outside and do something with our lives, or read a novel.
But I disagree with your premise, nearly every show on earth has a point.
Walking Dead - Survival
Lost - "We've got to go back"
Life on Mars - Getting Back to 20XX
Sherlock - Something to do with personal growth?
Okay I'm not sure about Sherlock. Or Robin Hood. And I'm a little drunk.
But I dont get Doctor Who anymore. What's the point. What even was that episode? 2D Monsters that leap out of the fecking walls? Amazing. Awesome. Should be fecking brilliant. And you know, it wasn't too bad. That was some semi-freaky shit for a childrens show.
Except I don't get what the point is at the moment. I just don't. I can actually tell you what the point of the story of Digimon Season 1 and Season 2 was, better than I can of what the hell Doctor Who is about at the moment. Digimon Season 1 was about a group of kids taken to a digital universe where they befriend a "Digital Monster" who each turn out to be linked individually to them in some way. With their Digimon they have to battle sick digital monsters, save the Digital Universe from the evil guy who is trying to take it over, and then something about saving physical real-world Japan where I get confused. Season 2 was similar except it had new kids, and all the Digital monsters couldn't digivolve for some reason so they had to do some sort of sideways armour evolution shit. It didnt really work but whatever.
Doctor Who? He's a 2000 year old alien who goes around saving the earth from monsters in his mystery machine with his friends and a robot dog. That's not the bad part. Thats fine, I'm excited by that. Thats actually great. No problem there.
Except they've basically killed the show by making Doctor Who dark and old when he had no reason to be dark and old. This seasons overarching storyline consists of a random women saving the Doctors enemies and asking some of them questions. And Clara moaning. And the Doctor acting old. There is no personal growth for the Doctor. He hasn't actually changed the entire season. It's been a season of personal growth for Clara: She is the main character at the moment. Which is fine. Except I have literally no idea what the feck is going on. Not in a normal Doctor Who kinda way "Christ that was confusing, timey wimey worm-holes causing weeping angels to get stuck in a black hole that created the earth?" That's fine. That's a doctors who fan's bread and butter. I just have no idea.
It's always been a "monster of the week" show. Except now its a "monster of the week" show that there is literally no reason to watch. It was certainly never worth watching because it was good TV. But now it's not worth watching because it's not a show about the Doctor and his battles with Darlaks, Cybermen, Time Lords, etc. It's a show about Clara and her battle with an old friend who has changed, and her boyfriend who doesn't want them hanging out.
