From an adult's viewpoint - I found this "arm-chair" cosmic voyage documentary (from 1996) to be only marginally educational when looking at it from a strictly scientific perspective.
I repeatedly found that a fair amount of the information being recited here by its bored-sounding narrator was, basically, just recycled data and second-hand knowledge which, of course, was made to appear significantly more interesting by an onslaught of dazzling CG imagery.
And, speaking bluntly about some of this science-documentary's computer graphics - I certainly wasn't all that impressed a lot of the time. I mean - If you ask me - There were certainly times when some of these glittering images actually looked downright hokey and, yes, almost laughable to this viewer.
Anyway - I'd say that the only thing that saved this IMAX "Cosmic Voyage" presentation from eventually deteriorating into a literal snore-fest was its short running-time of only 35 minutes.
