I am not reviewing the amazon copy since it has not been released yet. I bought my copy from The ABC Shop in Australia so it is possible that any extras may differ. There are no extras in the Australian release. There are 10 episodes in this series, so good value. While I still love this show, I found this series subtly different to the prevous ones and it took me time to get used to this. Analysing it, I think that series five focuses on the personal relationships more than previously, and there is more conflict among the characters. The focus seems to me to have been taken away from the animals compared to previous series. I also thought there was more cutting from one scene to another. I thought that, at times this made it difficult to follow the characterisations being developed. Hayley Mills is in all of the episodes except for episodes 5,6, and 7. In this series, she is looking great. and she is an active, likeable and pivotal character in the series. I now can't imagine this show without her in it. I think that the tension in the series bought about by relationship conflict is not an attractive quality for this type of show. For me the tension between man and beast was exciting in the past series. Even though I didn't enjoy all of the conflicts, I couldn't possibly give this series anything but 5 stars because it is so good. And the acting is excellent.
