It is very hard to brew a good lager, like the good Helles style famously brewed in Bavaria. I've been on a mission every time I come to the US to find good Helles, and I found two places that get very close:
This place in Seattle: https://maps.app.goo.gl/czPMtm4xkunkopEc8
And this in Weaverville: https://maps.app.goo.gl/wuNS33EcQ1qC9zfb9
But quite often even if they advertise the beer as German style Helles, it has some quality that makes it very different. Usually it's sweet or even hoppy. I think for an american a special beer should have a special taste, but a good Helles is just very fresh and crisp beer.
Edit: and Becks is one of the worst beers in Germany in my opinion... At least nobody tries to sell overpriced Sternburg here.
