I saw it last night, and have mixed feelings.
I agree that it needed some editing, and probably an adjustment to the plot. Brand’s “love” speech was cringingly bad, as was the callback later while Cooper was tesseracted.
Some parts just didn’t seem to make sense, as though there was a subplot that was cut. And looking at the pieces that were left, I can sort of reconstruct what it was supposed to be. I think there was a major backstory/subplot/theme surrounding Anne Hathaway’s Brand character that got left on the cutting room floor. Her character was supposed to be counterpoint to the Cooper/Murph relationship.
Why did they lose Doyle on the water planet? He was way closer to the ship when Brand got stuck, and he didn’t try to help her. He just sort of waited around until the doors closed? Or something? What if he actually did go to help her, and there was only enough time for TARS to save one of them, and he sacrifices himself for her.
Why did they lose Romilly on the frozen planet? There was the standoff between Mann and Cooper, and then… explosion! I guess Mann rigged the place to blow to protect his secret? Or something? What if there was a scene where Romilly tried to stop Mann to save the others.
I think we were supposed to see, in Brand, that sacrifice for someone else isn’t enough. It’s not enough to love someone or something so much that you sacrifice yourself so they survive. You also have to be with them, or they are alienated by grief.
The robots were excellent. The high point of the movie, and I will love it for that reason despite its flaws. I honestly can’t get over how good their concept and execution were. They managed to give TARS and CASE distinctively different personalities, which is hard to do with mostly-CG walking monoliths. All their dialog was tightly written. I loved the many homages to 2001, including the fact that locking the human out of the airlock is the right thing to do in this movie. It just all worked so well.
I thought the time travel thing was fine in concept, but as executed, required stupidity on the part of the characters. Once we realize that the ghost is actually communicating information, it’s basically screenwriting law that it’s going to be one of the two characters communicating with it. So it would make much more sense if Cooper, on the other end, were somehow limited in what he could say. Rather than Cooper sending “STAY” for, really, no good reason, there should have been some external pressure on him. Some way to send a message that was misinterpreted at the time, then reinterpreted later. But the coding theory explication scene would probably be even worse than the relativity ones.
I agree that finding a new planet as a solution to the blight was sort of weird and doesn’t really work. But it’s maybe worth it for the thematic resonance. The Dust Bowl is enough a part of the collective consciousness that it’s effective shorthand. You see the dust and hear the depression memories, and you can say “Ok, this movie is Okies in Space” and you have a solid foundation to build on.
Finally, the movie got a lot of little things right. “The World Famous Yankees” playing for a crowd of 100s was great, as was the dinner table laden only with corn products.
