9/10 Grade for the 720p HDrip Experience: Perfect for rewatchers and first-timers alike.

We meet nine-year-old Sheldon Cooper (Iain Armitage, delivering a miraculous performance that channels Parsons without mimicking him). While his father George (Lance Barber) watches football and his brother Georgie (Montana Jordan) teases him, Sheldon sits quietly, calculating the square root of pi. The inciting incident is simple but perfect: Sheldon discovers his father has not been attending church, instead sneaking off to eat sausage and watch the game in his truck.

Sheldon, incapable of lying or understanding social nuance, announces this at the dinner table. The fallout is immediate. His mother Mary (Zoe Perry, uncannily like her real-life mother Laurie Metcalf) is horrified. His father is humiliated. And Sheldon? He’s confused. He was simply stating a fact.

On September 25, 2017, television history took a nostalgic step sideways. Young Sheldon , the prequel spin-off to the mega-hit The Big Bang Theory , premiered with an episode simply titled "Pilot." For fans who had spent a decade watching the adult Sheldon Cooper (Jim Parsons) torment his friends with his rigid intellect, this was a chance to go back to the beginning—to the hot, dry plains of East Texas, 1989.
