Thaidakar the Ghostblood

Okay, yall, idk if this idea is original because I have a feeling ideas very similar to this have been thought of, but I still think it’s cool.

a robot or an alien has been assigned by their master to read loads of literature and such from an old species that’s been extinct for a thousand years. This species was humans from the planet Earth. The alien is sending reports to their master about the media they consume and what they think about humans from it. They would like read LotR and Narnia, then like watch Inception and read old myths. They would arrive at things like Lord of the Flies in like the middle of the book and go “humanity sucks.” 
the novel would just be the reports, so in an epistolary format. It would probably be a short story. Wouldn’t that just be a lot of fun? Doing the research for it would just be great.
