The "spy" robots are a gimmick.
I ask: who is taking all the shots of the robots themselves? Who is taking all of the non-robot shots of the animals? It would seem that the "normal" camera shots were just as close to the animals as the robot shots.
The vast majority of the video in each show is NOT coming from the robots, but from ordinary camera footage.
Having said that, the show itself is a good wildlife show, with interesting information, although not much that is truly unique, and some of the robot shots are pretty impressive (such as the shots from within the mass of butterflies). This keeps the rating from being a "1".
Overall, I dislike the way the whole thing is based on a gimmick.
