This series shows some excellent filming of wild predators in their natural environments, with great use of all the latest technology to get close-up shots and to follow animals running at fast speeds. The editing and overall production are pretty good too. However, we don't learn much that we haven't already learnt from previous wildlife shows, and the approach is one which will appeal to the general public rather than the more scientifically-minded viewer. I would have given the series an 8, but the thing that really spoiled it for me was the choice of Tom Hardy to do the commentary. Not only is the content of his commentary fairly tedious and a bit anthropomorphic at times, but he sounds like some TV presenter from the 1950s or 1960s speaking in the RP of those times. Is that his natural voice? Is he trying to sound like David Attenborough? If so, he fails. He comes over really plummy and traditional upper class, and you would have thought that an actor of his experience could have adapted his voice to something more 21st century and cosmopolitan. It's really irritating, and I had to watch with the sound down after a few episodes. If they had to employ a posh English bloke to do the commentary, I think I would have preferred Benedict Cumberbatch.
