Why a live audience? Bad idea!
They’re switching back to the same multi-camera format and filming in front of a live audience like Big Bang Theory.
That worked for TBBT because it was a standard sit-com.
But going with a single camera format was a smart idea for Young Sheldon because it was a different type of story and more realistic that worked better without laughter.
Reverting back to a sit-com format won’t work.
