This is escapist fare, aimed at the box-office, a fairy tale based on science. The science behind it (black holes, worm holes , relativity) is professionally certified for correctness. It could be gleaned from Stephen Hawkings popular but difficult book. The story therefore has a fig leaf of plausibility, implausible as it is: a daughter ages past her parent, and inter galatial worm-hole travel. The movie itself, its scientific kite string notwithstanding, is a far fetched yarn designed to accompany a tub of pop corn, and keep the mind in tether for nearly three hours. Its a film without soul, purpose, or artistic merit; it could well be contrasted with Kubrick and Tarkovsky's ventures into the genre. The best part is the beginning on Earth itself, as environmental disaster closes in and a food crisis hits the race, necessitating immigration into space. From then onward it is more on the lines of Marvel Comics. The house was unusually full, and there was a round of applause from the audience! So obviously it is going down well with a section of people. It does have an educational aspect in terms of environmental concern and cutting edge scientific theory. I can imagine many an animated discussion taking place about it.
