I tend to agree. I've always thought it would work well as a TV show in the more heady days of streaming (let's say 2012 - 2020) when networks and studios where it still felt like they had some room to take more risk. It's more towards the end of the last TV "golden age" but an adaptation like something like Apple's take on "Tales from the Loop". Not brash or loud or too formulaic but somehow still got made
I loved "Tales From the Loop", and wished they'd made more. It has a kind of atmospheric sensibility that sticks (with me, at least) long after the details of the plot are forgotten. That's appropriate, I guess, for something based on a portfolio of paintings. It's a hidden gem that I enjoy recommending.
