I think people are overselling it. Typical British tea isn't amazing and it isn't trying to be. It's more like a simple slice of bread and butter when you're feeling peckish but there's nothing else to eat. It just hits the spot. Once you've acquired the taste, you experience it differently. Spend an hour walking home in the rain, get home and change into your jammies, then curl up on the sofa with a nice cuppa. Then it's amazing.
