When I first read about plans for a TBBT spinoff, I did not think that it would work in a million years.
Maybe the reason so many people are disappointed is the huge difference in tone - and the fact that young Sheldon is way too cute.
While TBBT is more or less a nerdy version of Friends, Young Sheldon is more like a classic family comedy with typical family problems and the special task of raising an Asperger genius.
The key ingredients are the same as in TBBT though - fresh humor, well defined characters and a brilliant cast.
For me the best new show of the season.
