Overall, I'd say pass unless you, like Blackwell, see all the beauty in these places. And want to read about pooping outdoors.
This sums up Blackwell's thoughts about these polluted places pretty nicely, and why they are intriguing to him:
"I love the ruined places for all the ways they aren't ruined. Does somebody live there? Does somebody work there? Does anybody miss it when they leave? Those places are still just places." (page 226, hardcover edition)
