It’s always a struggle for me to accept that many people actually like graffiti. Maybe graffiti can add flavour to a city if it’s really drab and ugly (although I’m not too sure about this), but it only defiles cities which are aesthetically pleasing and beautiful. The technicality of graffiti has little to do with its appeal or it’s appropriateness. Something can be hard to make but still be garbage and/or misplaced w.r.t it’s surroundings.
