The question is unclear...

If the question is about drip coffee, most Italians (quite ignorantly) call it dirty water. The problem with Italians is that in general we are pretty provincial when it comes to food, and we assume that there's only "one right way" to prepare something. So, since for Italians coffee is only espresso, any coffee-based drink that is not espresso is bad. I had Italian friends complain that a wonderfully prepared Chinese noodle dish was "bad", simply because it didn't taste like mamma's spaghetti. In our defense, most drip coffee you get in the USA is, frankly, dirty water :). Get into any diner where the poor quality Folgers pre-ground coffee pot has been sitting on a heater for 3 hours, and that black liquid is undeserving of being called coffee. But you can have wonderful, single variety drip coffee, freshly ground and prepared. Alas, most Italians would still not appreciate it, because it's too far from their frame of reference. And, even if drip coffee will have more caffeine (per cup), they would be convinced that it's a weak drink (espresso extraction results in a much higher percent of solids and oils in the cup, creating a much stronger taste)

If you, on the other hand, ask about "Americano", i.e. the USA invention of taking a perfectly fine espresso and utterly ruining it with hot water, well, that should be a crime punishable by hard labor in a hot climate, with only stale Folgers as a drink. Espresso extraction is designed to extract a different flavor profile from the coffee beans than a good quality drip coffee (not to mention that the espresso beans are blended and roasted differently). It would be like taking a high quality Scotch whiskey and adding a full cup of water to try and create a wine. Alcohol-wise, you'd be in the right neighborhood. Taste-wise, you'd have ruined a perfectly fine spirit
