I can also respect the mastery that results in every keg of Heineken being functionally identical. I don't have to like the stuff. Or, heaven forbid, drink it.
1) The brewmasters of mass-market lagers are legitimate masters of their craft, because that style leaves absolutely no room for error and nowhere to hide mistakes. You can screw up an IPA and cover it in hops, at least to a point. You can screw up a porter or stout and cover it in malt. You have to nail a lager.
2) The product itself is still usually insipid, flavorless, and not worth drinking.
