Last week I took an opportunity to visit the space center since I heard some praising how well the show was.
Thus far, nothing supercedes the age old Passport to the Universe, narrated by Tom Hanks, not even Whoopi Goldberg's Journey to the Stars. Had it been available I would have bought the DVD.
I would say for Journey to the Stars, the narration and the plot and the effects aren't as pleasing as the other one.
