The Trailer Park

Maybe 90 minutes.

Some years ago, I looked up why movies were now being mostly made 90 minutes long, when the norm for so many years was close to 2 hours. I found the answer a bit ludicrous. ... It said something along the lines of, 'they found that most people felt 2 hours was too long to sit through a movie and that they found it easier to stay in-tuned to the movie when it closer to 90 minutes'

But oddly, it seems that nowadays, more and more folks are becoming lovers of binge-watching, and even watching multiple seasons of a show over a single day or weekend? Which could be years of episode viewing squeezed into hours? ... So 120 minutes is too much, but watching 36+ hours of a show in just a couple days works? Guess it all depends on the seat you're sitting in.

Yes, they do indeed repeat a lot, especially when they break it down into a series as you stated. My wife will walk in and go 'you watching that again', or 'we just saw that'? And I will let her know they are just showing it again, but in a different episode. And yes, David Attenborough is definitely a house-hold name. That's who I think about when it comes to nature programs or narrators. I'd say 95% of the nature shows I've watched were narrated by him.

And you're probably not too far off with the AI stuff either. With the technology we have today, and how fast it's progressing/developing, I'm sure there are already similar programs that can do some of those things, and it's probably not too far off before we start seeing them a lot more.

Kind-of similar in thought, just look at video games. It used to be you played a preset adventure, just trying to figure out how to get to the next stage. But everyone generally did the same thing to get through Now, they are making more and more sophisticated games where your choices not only dictate who you become, or how you look, but where the adventure goes from there. - Which I think is great, but it does involve so much more then just slapping together levels. The bad thing is, it takes so long to produce something like this and of quality, that most get upset on the wait time, or if it's dropped after years of work and waiting. But again, if you put it out early, and it's full of bugs, those same folks will be there just the same with their pitchforks and calling you all kings of names.

Sadly, the only person you can truly please, is yourself. When it's within your means, that is.
