Nooo don’t say that. As far as I can tell, North American culture is very rich with landmarks, fauna, flora, unique local culture, and many other things. I understand that there’s a lot of stereotypical stuff like fast-food, big tech businesses and ugly unoriginal buildings and such, but I’m open-minded enough to look beyond those things ^^.
I’ve visited the USA once; I went to San Diego and although I stayed inside the city, I visited a lot of places. I attended a scientific conference at the SD convention center (same one where Comic con is held), I visited the SD zoo, the Natural history museum, the Fleet science center (there was an exhibition on Mythbusters with a lot of their originals props!!), and the USS Midway. Also while I was there I went to a few bars and restaurants ^^. It was super fun and I got to see a lot of interesting things. I can’t know for sure whether I will ever return to the USA, but I learned about some of its culture while I was there and now I can better empathize.
