Had to write the personal view on this one, primarily to point out the level of the movie-subject underestimation. Firstly I would like to put aside typical movie-quality scales, like story-line (dramatization, scenario), length, acting, effects, so on. Its abstract subject is the one and only, but truly deep, thing that one should build opinion on. And from the beginning I didn't expect anything, but the artistic (maybe even post-modern) conceptualism. The exotic subject type explored before several times in the theatrical pearls like: "2001: A Space Odyssey" (it is slow too, simply to let us "imagine"/"trip-on" on many allegories in the movie), "Dark Star" (parody to the aforementioned), Tarkovsky's "Solaris", maybe even "Event Horizon". All mentioned are now spread over a half of century of movie making... Says enough about artistic freedom of such movies. And just to make it clear: I'm not comparing, except in artistic (and scientific) non-conclusiveness. Not a small bite for the makers only looking through that prism. The subject of the end of the universe itself is scientifically in the theoretical edge of modern cosmology and (even) some cognitive sciences to the measure of hard core artistic approach. And the one we have here bravely joins in - abstract and non-understandable. The boundary of space-time ends where it begins, could also be a holographic projection of Big Bang omega point or n-dimensional Klein-bottle perpetual knot.... Who knows? Trust me: not even Hawking nor any other cosmologist today. But, oh, what a great way to let our imagination construct (often wicked and far-out) narration! From time to time, we need to "brain-out" on this subject. So, let's not be harsh nor judge on this one neither!
