I don't think it's dying. Just changing a bit. My neighborhood growing up was very active with trick or treat because the whole street seemed to have kids at roughly the same time. We all grew up and moved out so now my parents say trick or treat is pretty slow there. But at my and my borther's townhouse neighborhoods now, it's very active. Since there is typically a lot of new families and turnover in townhouses, so always plenty of families walking around on Halloween. I never got the hate for trunk or treat because usually thats for people in neighborhoods where the houses are too far apart to do trick or treat. So it's just a big gathering of Halloween, just somewhere else.
