Three years is a long time to wait in the world of television. But, as with the new series of Stranger Things, the show about supernatural goings-on in the small American town of Hawkins, Indiana, there are some things that are definitely worth waiting for. Creators the Duffer Brothers recently revealed that this fourth series – the show"s penultimate – took almost two years of filming, and is nearly twice as long as any of the previous three. Netflix, which has recently been plagued with negative headlines about subscriber losses and stock prices, will be betting on the return of its flagship blockbuster series to briefly stem the bad press – and there is certainly no reason to doubt it won"t be another huge hit with subscribers.
