The culture is overrated only because of the image created by western media, how can the culture be "overrated" by itself? If it is overrated in certain environment (western media), it doesn't mean it is inferior to some other culture.
Now that you reworded your statement by adding "in certain ways", it is correct, as all cultures with no exceptions have its internal problems.
Hence the honest answer would be "Their culture is foreign to me, their problems seem to me more serious than of my own culture, I am not willing to associate with it"
