I watched both episodes. I, too, thought it odd that the kid, Jacob, never asked what a smart phone was, or flat screen TV or why cars looked so different. And, why do his parents look like grandparents would? Hasn't he figured out that the nice doctor is his baby cousin all grown up? And, no questions on why his best friend is now an adult? I hate when they don't answer the obvious.
Overall, it looks interesting!
