It all feels as dynamic and mould-breaking as it did 10 years ago. ER has kept itself fresh with regular transfusions of new characters, but it’s amazing how good the original cast was (take a bow Noah Wyle, Sherry Stringfield; Anthony Edwards and that Clooney guy). And we forget how radical ER’s multiple-stories-on-the-fly technique was, using long, fluent steadicam shots to give shape to a maze of powerful interlocking narratives. Holby City, get stuffed.
