Too long, inconsistent plot, ambiguous theme

Rating: 2/10 (19 April 2015)

I saw this film not on screen and I think it was right. The film's plot doesn't justify 169 minutes experience of sitting in darkness of movie theater.
For Science Fiction story with such a space-time scale, its' necessary to have more "superhuman", "unworldly" approach to theme. I don't like so much "2001: A Space Odyssey" with its too "unworldly" plot, but it was really on the path of the genre's tradition and norms.
Main stream Sci-fi from the beginning has dealt with human being as part of long-term development of the civilization, with the intellectual dominance in it and its limitations (including its conflict with human nature). Such films as "Forbidden Planet", "Roller Ball" and even "The Terminator" belong to this stream.
Another stream was such that deals with future world or futuristic technology as convenient gadget to develop rather traditional plot of other genre in a new setting."Alien", "Star Wars" and even "Blade Runner" are in this stream.
Probably only a genius like Andrei Tarkovsky could take the third course in this genre. He made "philosophical" Sci-Fi, not so "unworldly" but with emotional warmth, suffering of human being in this world, on the Earth, in "Solaris" and "Stalker". But he didn't like this genre at all.
If a filmmaker or a writer want to tell a "human story" in Sci-fi,then it's better to do so joining the second stream. The third one is not the choice of "worldly" hit maker.
I think the plot of "Interstellar" can be much shorter to develop the family story. No such strange situation of "World's end" is needed to do so. Today we already know the facts of global warming, possible exhaustion of fossil resources, ecological instability, and the wrong course of our civilization in general. So it would be simple to state the crisis and to start the story of emigration or exploration from the very start(as,for example, in "Stalker" and "Blade Runner").
The film's plot was meaninglessly made prolonged and complicated by adding pseudo-scientific terms and gadgets, like 5th dimension, black hole and wormhole. If you cut all of them, the plot will still work for family story of an astronaut, only by using "cold sleep" technology.
In general, sentimental story with "time travel" fit better to "fantasy" than Sci-fi. And there are such films as "Somewhere in Time" and "Portrait of Jennie", both of which were FAR BETTER MADE than "Interstellar" , telling stories with very clear theme.
