This is a more than an "Old Documentary". This was a monumental look into the universe in 1999. We haven't seen something on this scale since the Cosmos series was released back in 1980. The series takes you further and further from Earth. It's an educational experience for anyone who's never really considered what lies outside the Earths' atmosphere. This goes beyond any definition you'll find in any book. You have a front row seat to how and what we knew in 1999.
I have to disagree with those who say its outdated. I think it's more important to leave it untouched, a time capsule of sorts, preserved as a bookmark in time. It chronicles the technology we had up to 1999. Sure a lot has changed since then but how else can new generations have any understanding of how limited our knowledge of the universe really was in 1999.
If i had to point out something negative it would have to be the narration. The version i remember had an America voice resembling Mike Rowe. All i can find is the narration Sam West did.
