I read Dos Passos trilogy back in grad school. It always felt quite cinematic to me, as if Dos Passos took Sergei Eisenstein as a model.
Although I have an allergy to most SF, I'll give Okorafor's "Lagoon" a try if you recommend it.
Perhaps it's time I went back to The Heart of the Matter - I haven't read it in 40 years, but remember I liked it.
The only Dos Passos I read - in the 1960s - was Manhattan Transfer and I don't think I managed to get to the end of it.
