You don’t have to like something to appreciate it. I don’t like the mindless scribble of graffiti (although I do appreciate the more clever forms and think they can be more honest and creative than some revered art hanging in galleries). Neither do I condone littering, particularly with equally mindless branded soft drinks. I can see through these things however when a composition catches my eye. Here is another case of isolated colours playing against each other. If you took away one of either the green door, red can or even the graffiti I don’t think it would have caught my eye as much.
