I think Interstellar was a very interesting movie, and I enjoyed it a lot. But there a two things I find damn stupid and really poorly executed in the story telling and so I must blame Nolan for that foolishness.

1: when he returns to a better future and now an old Murph, they pretty much show no true interest and her new family seem to just brush him off. I know, I know the movie sort of just explain this that she wanted to see him before she would die.. but I found that whole thing utterly poorly executed in the storytelling. Not least because the whole damn movie was about him coming back home to her... talk about an anticlimax

2: he went into the black hole and communicated back in time to her via some alien gizmo .... holishit wait what???? And no one care one bit what the hell happened. Yes again I know Murph said no one believed her when she talked about a ticking clock telling her the secrets of the universe... (did she really try to say that to her NASA peps)... but even Murph cared not at all how the hell he did it... truly this was the most mind blowingly fantastic thing about his whole tale... unbelievable miss in the storytelling .... and sooo easy to fix.

3: also, what about his son and his family line?

4: and then for some reason he goes to rekindle with Brand, because ... sure they love each other now... what, when was this ever shown during their travels? In fact, it was made clear Brand was in love with one of the stranded explorers whom she was believed to end up with... but ind the end, now Cooper was her love interest..... yes I know again that the movie showed us her love was dead and buried on that planet... but Cooper did not know this. Confusing.

5: why not send supplies to Brand first btw, I mean this better future seem to be pretty resourceful... but he just take off.

Okay, I said two things .. but still the movie could be brilliant and then just falls apart in this final act. In ways that could so easily have been fixed.

Am I wrong ?
