Three rich white kids decide the way to break free of their priviledge and controlling, materialistic mom is to burn down their fancy family home.
Their parents will just buy another one with the insurance money! There will still be money to send them to college. It's doubtful any of them have the moral character (or life experience) to simply strike out on their own, and even if they do, they're still white, good looking, entitled, and wealthy.
So .... what's changed? They only torched a lux home that will be rebuilt. (I guess they lost some family antiques, if you want to quibble.)
Yeah I wish they went a different way with it because the story was pretty good up to that point. I thought it would be Bill or Moody who set the fires because they were the only 2 who didn't snap before the last 1 or 2 episodes.
I don't think it's meant to be interpreted and taken in a literal way.
I think that sequence is rather suggesting an allegory, telling how Elena's three children are at least temporarily "burning the bridges" linking them all to their overwhelming mom.
All in all, I kinda felt sorry for Elena herself. And the McCulloughs arc's ending really broke my heart... though I'm totally on the left wing, politics-wise, I was definitely rooting for May Ling/Mirabelle to keep living with them.
I agree that I think it's meant to be metaphorical (why they did it). But the problem is that the kids who set the fire didn't understand it to be metaphorical because they had never heard the metaphor. It's Izzy who understands fire as clearing away the old and making way for regrowth, so if Izzy had set the fires (which I believe is how it was in the book and was changed for the tv series) then that would have made sense. But for the other kids to do it just seems random and spiteful, not to mention dumb, since they are burning down their own home.
In the last episode or two, the show seemed to really push a particular interpretation of its theme (eg that Elena's faults caused all of this), but I felt like it failed to defend the theme sufficiently in the way the characters were portrayed. In general, I prefer if tv shows don't come down too strongly on one side of their theme. Just let me watch and make my own decision.
I agree the older three kids' aversion towards Elena, and the subsequent reaction, looks a bit rushed.
All in all, when it comes to turning the allegory into a metaphor, it's like Izzy, as the younger child of the Richardsons, paved the way for his brothers and sister to turn against their mother's "liberal on the surface, actually WASP-ish" attitude.
That is an interesting interpretation. What I was thinking of with Izzy and the metaphor is that Mia gave Izzy the metaphor when she explained her artwork to Izzy. Izzy is a child who clearly has some mental health problems, so when she hears the metaphor, she internalises it, and you can see how she might enact it as a way to cry out for help. So if it were Izzy who had set the fires, then it would have made sense psychologically for Izzy, as well as playing into the theme about how mothers can sometimes hurt their children even when trying to do their best. By shifting the firestarters to the older children, none of whom the same underlying mental instability as Izzy (and more importantly, none of whom heard the metaphor), the show undermines that theme and makes the older children do something that doesn't really come off as authentic for them (in my opinion).
But, again, I didn't really buy into the idea that Elena's motherliness was superficial or racist, so the argument set up by the show just fell flat for me.
Anyway, what I was meaning first is the "fires" started by Izzy's siblings are allegoric, instead of literal. Just depicting a generation shift, between Millennials and late Boomers, and how those particular kids are taking some distance from an overwhelming mother (whom I still think isn't that bad a person as the series suggest, in comparison at least: Mia's not that better, let alone Bebe).
I know it's not "that kind of story", that it's set in reality, but that's the sense it gave me. It might even be a hint to Graham Greene's 1954 short shory "The Destructors".
