No. It is not. You are simply wrong here.
You can watch whatever you want to watch. Most adults want at least TV 14, but more R, MA, or above shows to watch. And this is even more true for a "general audience".
ALL of which are made for teens. Temple of Doom was never R rated. Poltergeist was PG. Gremlins, PG. Nothing you just listed was R rated.
Did you miss where I was listing PG movies from Back in the Day, to show they are not like modern PG movies?
ROTFLMAO
You really, really don't know what you're talking about. Like, at all.
Ok
Watch me use my Crystal Ball:
At some point they will make a D&D show. It will be lucky to even get a Pg-13 rating, as everyone will say "D&D is for kids" and they must "make a show for kids". Sure, they might try and spin it as fun for the whole family....but note that means fun for the kids only.
They will hire a D&D expert or two who "played D&D a couple times" and can "spell D&D". The D&D expert writer, will only think of "D&D must be about a quest". And everyone with the show will get locked into "D&D=quest". So with the small eight episodes, the writer will write a wacky, zany super PG D&D adventure quest movie, and then chop it down into eight parts.
The D&D group is sure to include something like a goofy bard, a strong female barbarian, a goofy wizard who can't spell, a strong female ranger/druid and a short actor to be a halfling fighter? who complains a lot. All the spellcasters will forget they have spells or something..except maybe once an episode. Most of the characters will have "cool" looking weapons....that they mostly don't use. And when they do, you can be sure it will be "taps" and just "knocking foes down".
So episode one is the lovable bard...cheating at a card game and gets caught. There will be a fun romp to catch the bard. The bard will not attack with a weapon at all and will not cast a single spell.....but will do things like put a bucket over a guards head or drop some banana peals to make the guards fall. "Somehow" the bard will bump into each of the main characters, and "cliffhanger they all get caught.
E2. Saved by the King. The world will be destroyed by the Dragon of Doom in 30 days....unless someone puts the Gem of Gygax back together. And only the wacky group can do this...for no reason. They have to not fight there way to a sage...who tells them the Gem was broken into four parts and scattered. This gives a nice arc for E3-E6 as each episode they go to a set place: the desert, the far north, the underdark and the tropics, to get the four gem parts. And for each spot...there will be some wacky zany adventure. Like in the tropics they will find a con man using the Gem part to win card games.....the COULD just walk over and kill the dumb con man...you know to save the world from the dragon of doom....but they won't. Instead they will come up with a wacky paln to play cards with the con man and (cheat) and "win" the Gem part. Adventure!
E7. they get back to the king and give him the Gem of Gygax....and surprise, What a Twist...the king is a bad guy! He summoned the dragon and now will absorb it's power to Rule the World! Or um Destroy the world? Or um, it does not matter. The poor group has a "we ave to stop him...um...because the story plot says so" moment and makes a wacky plan.
E8. They go after the king. Lots of turkey leg bonks, apples tossed to trip foes and other such PG "action" . Then they trick the king with some Scooby Do like plan.....the king screams "no, I would have done it if it was not for these medeling kids!" And the Gem, King and Dragon all go "poof" to make a happy ending.
Brace yourselves...
