haseebanjum85 One of the best documentaries I have seen ever! There is so much in the world that we don't see, some of which we are now able to observe due to the invention of specialized cameras.The different episodes make use of different cameras to show us what we are missing out. Special high speed cameras, infrared cameras, ultraviolet cameras, x-rays etc etc show us what our brain and eyes can't process but it's present all around us, the observance of which has led to making scientific discoveries.Richard Hammond (of the Top Gear fame) makes it very interesting. A bit slow and music throughout, which made me cut a point out of 10. Watch it when you have time and relaxed, it'll seriously amaze you. A must watch for science fans.

caddyshack75 It was good, but just too slow. They over-produced this, with just way too many cut-scenes of people & objects, panning around, that adds absolutely nothing to the 'science & nature' aspect of this.The first and third episodes were better, the second was nearly unwatchable. It was constantly trying to build suspense to what they were about to show, and spent so much time doing it that it became tedious.The narration pacing was horrible. The text was fine, but there are constant pauses every half sentence, apparently for dramatic effect and to push in all these barely-related scenes that had no real content. This was probably done because they only had a small amount of significant material and the rest is filler.Where they actually did display the science and images, it was fantastic, unfortunately I would say that was about 10% of the entire volume of time that you're watching the show. This could have been so much more, or, it could have just been delivered to us in 1/3 the time.I was left wanting more... not because I wanted more of the same presentation to continue, but because I wanted more 'meat'. I was disappointed in the end.
