If you have ever wanted to travel out into the universe, this is probably as close as you are going to get to fulfilling your dream.
The film contains spectacular 3D imagery based on real data and real science. And for a change, it's not gimmicky - it adds enormously to the experience by making you feel like you are really there. In fact, the whole film prides itself on the use of real scientific data to show audience what the universe and astronomy is really like - not some CGI artist's version of it.
Thoroughly enjoyed the film, and judging by the comments around me afterward, so did many others. It seems everyone has their favourite bit (and there are many bits to choose from) and the kids in the audience sounded super-excited by what they had just seen.
