This film is full of information. Frustratingly for anyone older than 12, you probably already knew a lot of that information. Aqua is Latin for water. Geosationary satellites orbit above a consistent area over earth. The visible light spectrum is only the tip of the iceberg of the electromagnetic spectrum. These are all things which I hope everyone leaves their teenagers years already knowing. Earth From Space does contain some enlightening statistics and visuals, but does little to expand the viewers knowledge base beyond the basic facts of the natural world which it takes so long to explain. The reason why it takes so long to get to its point because it gets bogged down explaining even the most basic facts to the viewer. This is great if you're a child, but for an evenly moderately educated viewer, the film simply moves to slow.
This film is ideal for young audiences. If you already have a basic understanding in physics, meteorology and satellites, then it probably isn't worth your time to sit through all the basic information until you learn something new, because there's nothing groundbreaking about the facts included in Earth From Space.
