It's easy to hate The Big Bang Theory. A lot of people do it every day without much thought as to why. So let's take a quick look at the Big Bang Theory, it's characters, and it's jokes and see what we can find out.
Not having read the article, I'd venture a guess that they're both completely different shows. The fact that it's the "same character" amounts to little when the age and setting are so vastly different.
YS is not my thing at all. Not saying it's bad for what it is, just not for me. The BBT I sometimes enjoy, at least moments here and there in the first few seasons. As with most sitcoms that I like (to varying degrees), I typically enjoy the early seasons and then lose interest the longer the duration.
It's pretty simple. The Big Bang Theory was a show more or less strictly for millennials, while Young Sheldon can be appreciated by older generations for its late 80's and early 90's setting and nostalgia.
I used the wrong wording there. It was intended for general audiences when it aired. What I meant to say was that I think in terms of nostalgic value and if somebody was to watch it now for the first time, millennials would have the most affection for it as it aired when they were of the characters age. But hey, I loved Seinfeld and watched it long after it aired.
But a lot of the stuff they talk about on the show - Zork, Campaign for North Africa, Magic: the Gathering clones, comic book heroes, and so on - are familiar to much older folks.
Sure, The Big Bang Theory has nostalgic references too. It's just that Young Sheldon has a lot more of them. But fair enough, I didn't have a point on that.
Well, TBBT has a laugh track, while Young Sheldon doesn't, which at least my boomer father always hated. So maybe I'm just colored by that and assume that older people are more likely to be turned off by shows that do.
Also, I'm not sure if it's right to compare the two shows just because one is the parent show on the other. TBBT is a light-hearted comedy, while Young Sheldon is much more dramatic.
