RE: Who are they?

Back then I saw a fraction of cinephiles criticized Interstellar for having such melodrama in a hard sci-fi film. I don't think they have to be mutually exclusive. I loved the relationship between copper and murphy, hell, some of the scenes were tear jerkers.

I remember writing a "detailed explanation of events and science behind Interstellar" back in 2014/2015, it was a really popular post on facebook. :D Looking back, sometimes it feels silly writing stuff like that which have no relation to cinema, then again it may have helped people a bit, introduced them topics such as nature of space-time, relativity and such. Specially to people who only read these chapters in school to pass but never realized what they are about.

By the way, if you liked Inception, you must see Paprika (2006). Nolan got the inspiration from that animated film, and also recreated some of the scenes from the anime in his film. While the implied sci-fi in Inception is well developed, from a cinematic perspective, I'd say Paprika is better.
