I always remember the scene from Interstellar where, near the end of the film, Cooper comes back and is reunited with his now aged daughter in the hospital where she is dying.
I think that scene, FAR more than any other, revealed Nolan's shortcomings as a human being.
She is surrounded by family, presumably Cooper's grandchildren and great-grandchildren, all of whom would have grown up hearing about her father, who had managed to do the impossible and harness gravity itself to send the much-needed information that would make their survival possible.
Rather than be amazed and loving and happy to see him, they all act like complete strangers and leave without so much as glancing at him.
Murph, his daughter, who had spent her whole life working in unknowing collaboration with her father, whom she has now known for decades to have not deserted or failed her, barely has thirty seconds to spare for him, and essentially shoves him out the door to go hook up with spacebabe on the planet they're headed toward.
...and he goes, leaving this huge family he takes no time to meet or get to know, to romance a woman whom he's known (from his perspective) an extremely short time, and until now has had very few seeming indications of romantic interest that Murph just seems to "know" psychically.
This is awful writing. This is awful characterization. This is an inability to allow for basic human drives.
