SITCOM PREQUEL

Young Sheldon, 8.30pm, E4

THIS nicely pitched new prequel to The Big Bang Theory (which returns at 8pm) follows genius Sheldon (Iain Armitage, pictured) at school. On his first day, he turns up in a bow tie and is very honest with everyone. Bad move. There’s a depth to this show that should give it mileage, and the humour is less cartoonish than that in Big Bang.
