One episode features Jane having trouble learning to drive. Some viewers have seen this as playing into the stereotype that women can't drive, especially due to some of George's comments in the episode. In a later episode, Judy successfully learns to drive and nobody implies that she won't be able to because she's a girl. Furthermore, Jane is occasionally seen driving.
Some of the fanbase don't like to acknowledge the '80s seasons. Many different reasons include the direction of the studio in the '80s, the more sci-fi storylines, or the addition of Orbitty.
Inverted in Mexico, where the original '60s version is normally ignored, partly because of the time skip between the '60s and the '80s version and partly because Mexican broadcasters normally put more emphasis on the '80s version, with reruns of the '60s version being much rarer.
"Funny Aneurysm" Moment: Remember how funny it was to see George complain about pain at work when all he did was push a button? Nowadays, Carpal Tunnel Syndrome (pains brought about by repetitive tasks such as typing on keyboards) is a concern.
The treadmill gag at the end. Now there really IS a dog-walking treadmill.
The televiewer is remarkably similar to an LED TV.
Videochat can be seen as the precursor to Skype.
One episode features a robot vacuum. Many years later, we get the Roomba.
The pilot features the Peek-A-Boo Prober, a little robot which will examine George from the inside. Sounds just like the Spider-Pill, doesn't it?
Jerkass Woobie: Spacely. Despite being a Mean Boss, he often has to deal with his snobbish wife and a bratty half pint son who has little to no respect for him, and has to deal with his company rival W.C. Cogswell stealing his ideas before Spacely puts patents on them.
Newer Than They Think: Comparisons to Blondie are almost inevitable when discussing the show today, but these went completely unnoticed during the show's original run in The '60s. Reviewers instead focused on the far more obvious parallels to The Flintstones.
Nightmare Fuel: The "Robots Revenge" episode from the 1985 revival. George pisses off one robot who then issues a "code red" where robots and machines everywhere turn against George, including Rosie (though she ultimately can't go through with it)!
In the Haunted Halloween episode, Dr. Scarem was a bit creepy and wanted to "add" Orbitty to his collection but it turned out he just wanted to make a costume in Orbitty's honor.
Older Than They Think: Some fans mistakenly believe that RUDI was created for the 1980s revival, when he actually did appear in one episode of the 1960's season, and only received more prominence in the later seasons.
The Scrappy: Orbitty. Even the people working on the series hated him, and John Kricfalusi has gone on record as having frequently tried to work in scenes where he'd get abused in the episodes for which he was an animation supervisor.
Seasonal Rot: The 80s revival seasons aren't nearly as popular or well-received as the original 60s season.
Values Dissonance: In the second season: the family is watching TV one night and learn that the priest who married George and Jane was actually a con-man, and that this one thing somehow meant they were never actually married. This means Judy and Elroy are bastard children. How did this episode get green lit?
Another episode dealt with Jane getting her driver's license, which is treated like a living nightmare for everyone else involved simply because she's a woman and "You know what they say about women drivers!"
We're Still Relevant, Dammit!: The music in the 80s revival is about 30% Simmons electric drums, including having them dubbed into the iconic theme tune.
George, obviously, considering he has to put up with Mr. Spacely as a boss.
Also Astro whenever George is too harsh with him and especially in "Elroy Meets Orbitty".
Broken Base: The basic idea of the movie itself is pretty divisive. Those who wanted to see The Jetsons again after so many years would be disappointed to see them only promoting wrestling. There are others though who are at least open to the idea, and are willing to at least give the movie a try.
Character Rerailment: Some people complained about Spacely going too far in the previous movie with him knowingly destroying a secret civilization. This movie returns him to his Jerk with a Heart of Gold personality by making him gruff, but reasonable under the right circumstances and acknowledging when others are doing well.
He Really Can Act: Trevor Devall is not usually known for voicing young boys, yet he gave a really good performance as Elroy, capturing the snarky adorkable side to his character. Some people even went further and said that out of all of Daws Butler's replacements, he's the best.
