We’re big fans of plausible fiction, and the way Interstellar’s future is presented is a good example of that. Rather than some mysterious plague or Third World War that has turned the world into a post-apocalyptic cliché, it’s just normal people doing what they need to do to survive while trying to maintain a sense of normalcy. Plus, as noted, the story does a nice job of balancing some weighty science fiction by keeping concepts like love and family front and centre throughout.
