This is brilliant! Several perspectives of a brief point in time. Not based on any real characters, just a great story. The soundtrack really helps it along. I'm sure there is an Oscar in it for Christopher Nolan, since he wrote, directed and produced it. And an Oscar for the score maybe, it is something very different to your usual orchestral score. Technically, it is orchestral, but mostly consisting of sounds akin to heartbeats, ticking clocks etc.
Perhaps an only failing, for some people might be that there is no strong single lead in the movie. but that is the point of it I think. A bit like say Tora, Tora, Tora but you don't have to sit through two hours of movie to get to the exciting bit at the end!
This is a 5/5 for me (",)
