They wanted to hit home that "Nostalgia is toxic". And how it's easy for a White person in America, in particular a White man, can long for the past but hey never think about how it was for Black person, or person of color, or a woman back then or delude themselves in thinking it was better for them.
I don't see why having it come out slowly would preclude that. Have Angela have random flashbacks that incapacitate her at key moments showing nostalgia's detrimental effects (like have one slow her down as she's chasing Lube Man for example), and further have memories pop-up to highlight that disparity you're talking about (some modern day white privilege contrasted with something happening to Will in the past as Angela looks on at both).
