I block all ads on my devices, don't watch tv live, etc but I do like outdoor advertising. It's different. All the loathing here is a little surprising.
From guerilla stickers on the bus and posters on construction site fences to entire buildings wrapped, complete with props (like a car hanging from the side) it makes cities look alive. LED signs, especially the larger ones capable of showing graphics, and (my personal favourite) proper, old-school neons make cities look like cities. Billboards cover unfinished structures or designs from architects who should have never been licensed.
Maybe it's all the crappy communist architecture here but even places that evolved more naturally generally gain. Sure, there are some old towns, picturesque villages and so on but that is nowhere near the majority of the space inhabited by people.
