"Interstellar" has a very high IMDB rating but doesn't live up to the expectations, at least not to my expectations.

Meant to be a tribute to "2001: A space odyssey" (1968, Stanley Kubrick) the film fails. This is true for the film as a whole, but also the scenes with respect to the wormhole and the black hole are inferior to the (more abstract) psychedelic scene at the end of "2001 ...".

An important aspect of the film is that characters going on a space mission age less fast than characters staying on earth. This enables paradoxes akin to time travelling. Although the paradoxes in "Interstellar" are scientifically better founded than for example the time travelling in "Back to the future" (1985, Robert Zemeckis), the consequences are less appealing to the imagination. The morse codes in "Interstellar" are definitely less spectacular than Michael J. Fox who, being in the past, has to extinguish the amorous advances of his future mother because this advances threaten his conception by his future father.

By the way, also the science behind "Interstellar" is not entirely clear to me. Time going more slowly when you are moving faster does not mean that it is possible to go back in time.

One last remark about time. In "Interstellar" time is treated as a scarce resource by the astronauts. They know their loved ones age more quickly than they do and they want to be back on earth before their loved ones die. How different are the astronauts coming back to earth in "Planet of the apes" (1968, Franklin J. Schaffner). They are not really interested what year it is, they even don't know for sure if the planet on which they have landed is the earth.

The strong point of "Interstellar" is the situation on earth. In stead of a big apocalypse (as for example has happened in the already mentioned "Planet of the apes") the ecological situation is steadily detoriorating and the earth is slowly becoming one big dust bowl. This kind of dystopia makes "Interstellar" a typical film for a period in which global warming is (finally) seen as a big problem.
