I'm rewatching season one. Despite the left-liberal slant, it's still more edgy than anything I've seen in what I suspect is the comedy scene of current year. Not that I've really bothered to check things out. Is there anything really worth checking out?
Since the 'Summer Of Love' of 2020 the streaming services (Big Tech) have pulled many episodes featuring blackface as a gag. Most of them from shows of the same time period.
Apparently, even 'Golden Girls' did it at one point. Imagine that. 'Golden Girls' being more edgy than current year.
Even the '10 Jokes From 30 Rock That Have Already Aged Poorly' article on Screenrant, predictably written by a female blogger, is more a promotional ad than anything else. (Although, those tranny episodes were truly cringe. How could they not be?)
Social media, Big Tech and the Democrats really did a number on society.
Leonard IS a beta who still managed to get the hot chick. Sheldon even mocks him for being a soy-drinking beta. That's all part of the ongoing joke. Leonard should never be portrayed as an alpha, dominant male, but you're still expecting him to be. You're completely missing the mark.
And the women DO make the boys' lives better. Trying to find and manage good male/female relationships is part of the arc to the entire series for all characters. Frankly, it's also often done with a good message -- a man is better with a woman and vice versa. Raj and Stewart often serve as foils to that message.
However, the women are not shown to be smarter and more capable. Penny is portrayed as dumb throughout the entire series. She's an incompetent waitress and failed actress until, much later, she's given a long-shot opportunity to become a sales rep. She almost bombs at the interview until she bond's with the boss over their bitchy associate, Bernadine, which is just enough to rationalize her getting the job. Penny succeeds as a rep because she uses her sex appeal, not because she's a talented sales person, something she's fully cognizant about.
While Bernadine is competent and intelligent, she's never portrayed as smarter than Howard or the males. Amy is the only one who rivals their intelligence, and she's even more awkward and socially inept than the boys.
Bernadette is portrayed as smarter than Howard. She even mocks him for not having a PHD like she does. She tells him verbatim she is smarter than him, and he agrees.
While Amy is socially awkward she mellowed over time. They had whole episodes dedicated to how awesome the girls were. And Penny gets a job as a manager and excels at it.
I see your PhD and raise you my NASA credentials
Okay, I'll concede that point, but having no PHD is an element of mockery Howard receives from everyone. Despite this, he's a highly successful engineer and astronaut, which arguably outshines pretty much anything Berny is shown to accomplish.
This is true too, but it's also an acknowledged part of her personal character arc. She attributes Penny to making her "cooler" and more down to earth, but for most of the series, she's a very submissive and awkward character which also makes her vulnerable and entertaining.
There are comparable episodes for the boys, but I'd still point out that this approaches nothing when measured against the current era of girl boss media. It's not even in the same league.
All this is to say, again, that compared to this era of media, TBBT has some positively based moments. The series started by them cracking jokes about the tranny who used to live across the hall. Good luck starting with that today!
