Heart of Darkness

I DONT KNOW WHAT I THINK ABOUT THIS BOOK! Is the darkness the horrific treatment of the Congo at the hand of the Belgians, or is it a dated and colonialist metaphor for primitivism??? Is it both??? Are we supposed to agree with the perspective of the narrator?? Are we supposed to criticize it?? I don't know! Still hard to read dehumanizing portrayals of the Congolese whatever the intended reading. Also so much tell and less show. Idk. I'll be thinking about it a lot at least.
