I have a problem with the reviewers complaining about how Sheldon is such a brat and at the same time say they watch TBBT. If they watch that show then they must know Sheldon is a brat. In this show, though, we have a 9 year old version of a bratty Sheldon. In both cases he isn't bratty because he's spoiled or mean hearted. He's bratty because he's a genius and a social simpleton. That's the point.
I Iiked the show right off but I can also say that it has improved as these brief, less than 30 minute, episodes are able to develop the characters and relationships more. One reviewer complained about the lack of character development after only watching the first show!
I also think the actor playing young Sheldon is doing a great job. As with the adult Sheldon the young Sheldon is sincere, wants to be good, knows his own mind but also knows that he doesn't understand social norms and so listens to those close to him although he reserves the right to not accept those norms. I enjoy the family dynamic and the situations that arise because he's special. This family is much more realistic than the Malcom in the Middle family, a show one reviewer touted as being at a level this show couldn't come up to. The characters in MITM were ridiculously stupid. The characters in Young Sheldon each ha ve a unique personality and do things that you have seen others do or can imagine others doing, like Sheldon's brother trying chewing tobacco, repeatedly spitting it out in disgust then saying "I must be doing something wrong".
The writing warms the heart as we watch a family moving past disagreements and difficulties caused by their special Sheldon - all realizing that they love him and he's family which is more important than those disagreements and difficulties.
