a a physicist and talk about blackholes and cosmology get my heart racing . however i find this presentation too slow and not pack with enough information for the interested layman ( who be most likely to see it ) . if you have more than a passing curiosity in this sort of stuff and go to the library and check out some book . you will find they explain current scientific cosmology with far more detail while at the same time fill you with more of a sense of wonder than this movie do . also to set the record straight represent hawking be not consider the great mind or the world smart person a commonly assert even among the user review here at the imdb . hawk himself have comment that it be rubbish . it be just medium hype . they need somebody to fill the role model of disabled genius . at least i be disable . to be fair and he be probably a genius but among history great scientist and people like einstein and newton and gauss and and many others easily be even more highly regarded . this be not to disrespect hawking who be a undoubtedly a great scientist but rather not to disrespect others who have do even more than he have . anyhow and see the movie if you be truly into science . but if not and i think it would be bore for you .
