This is a full series shown in TV by the History Channel. It may be the first and only series in 3D in which all episodes of a season are in that format; in fact, there are two seasons in 3D: season 5 and 6. If you like this kind of documentaries on TV, imagine if all of them were in 3D, you can watch this documentary and feel like the 3D were the accustomed format of TV shows.
The images shown are constantly amazing you, everything is full of depth, including the narrators, a visual spectacle for your eyes.
There is a 3D Blu-ray available including 3 episodes instead of all the season (but already more than 2h run): https://amzn.to/3PF6Ysr.
If somebody knows a 3D channel or other way to watch again the TV series in 3D, please, tell us in comments.
