text: As a physicist, talk about blackholes and cosmology gets my heart racing. However I found this presentation too slow and not packed with enough information for the interested layman (who is most likely to see it). If you have more than a passing curiosity in this sort of stuff, go to the library and check out some books. You will find they explain current scientific cosmologies with far more detail while at the same time filling you with more of a sense of wonder than this movie does. Also to set the record straight: Hawking is NOT considered the "greatest mind" or the world's "smartest person" as commonly asserted even among the user reviews here at the IMDb. Hawking himself has commented that "It is rubbish. It is just media hype. They needed somebody to fill the role model of disabled genius. At least I'm disabled." To be fair, he is probably a genius but among history's greatest scientists, people like Einstein, Newton, Gauss, and many others easily are even more highly regarded. This is not to disrespect Hawking who is a undoubtedly a great scientist but rather not to disrespect others who have done even more than he has. Anyhow, see the movie if you are truly into science. But if not, I think it would be boring for you.
