I just saw the film via cam torrent. I'm going to put out my statement. In going to try to ignore all the flaws that were deliberately left there to make a good plot(ie: 4d scene)
My criticisms:
The beginning interviews with the old people talking about dying plants seemed unessesary. Especially since you only get the reason why such interviews were being made at the very end of the movie.
When cooper and daughter chases down the drone, they talk about it being from the Indian military and they mention that Indian military headquarters went dark 10 years before. They make no mention of any other part of the world or any other part of the U.S.. Hell! They don't even say where the movie takes place(I presume it is Texas because of low gravity and plains). They don't give any basic explanation as to why the Federal Government collapsed or what emerged in its place...the characters always refer to it in a past tense.
When cooper finds the hidden base, they are confronted by a that robot. And instead of being arrested by local authorities, they are taken down into the base. How is the base hidden? Do the local authorities know about the base...especially when it's large and swarming with people and robots. How are they able to keep launches secret? How did they keep the last 12 launches secret?
When they launched the spaceplane into orbit, they used a 2 stage rocket plus the engines on the spaceplane...Yet when they were on other planets, they were able to do SSTO easily.
Wormholes are unstable when close to planets and stars... Unless they are of sufficient mass themselves. The minimum distance for a stable low mass wormhole would be close to a hundred au away. The wormhole does have mass since they claim that an observation probe has been orbiting it. Is the wormhole still there after the mission is done?
How did the ice planet have ice clouds? Given the high gravity(0.8g) I would think they wouldve collapsed by now.
In the final scenes, they show an oneil cylinder in orbit around Saturn. Who governs this station? Does the blight carry on to the space station farms? Is NASA still needed for the habitat? Is this station even part of the U.S.? Why has technology and culture remained stagnant even though they now can build world sized structures. Has earth been abandoned or is there still people living there?
To be honest, based on the state of the world economy, which is now agrarian, it would seem that they would have an extremely hard time building new worlds when they barley possess enough infrastructure to find a cure for this blight or build domed cities on earth. I doubt they would even be able to jumpstart a space based infrastructure and build giant stations in the 84 years stated.
Good things:
The movie overall was pretty awesome. I wish i could've seen it on the big screen. I really felt like the world was ending during the earth scenes. I also felt really emotional when thinking about the 1 person exploration missions that we're going on. I still can't come to grips with fact that a person is carrying out a long duration suicide mission so far from earth. I still am thinking about that girl left on that habitable planet preparing to impregnate herself with the embryos to start life over again.
The movie(even with its minor scientific and plot flaws) managed to impress my simple mind. And it is now ranks close to 2001 in terms of scientific accuracy, artistic expression, and plot.
