Contrary to other reviews posted here, I didn't actually like this series very much at all. I have to admit that so far I have only watched the first episode, and am reluctant to watch anymore. I am a great lover of wildlife and completely adore orangutans, being lucky enough to have visited Borneo and witnessed them in the wild. I really am in awe of Lona and her work with the BOS but I don't think this series really focuses on that aspect as much as Orangutan Diaries 1 & 2 (which I loved), although this episode did show a very touching scene between Lona and Cha-Cha. I watched Orangutan diaries before buying this series and I really think that Orangutan Island doesn't compare at all. The American narrator is annoying, and in the American way, over-dramatises everything (e.g. 'Cha-cha must fit in with the other orangutans on the island, or else she will have to leave... NEVER TO RETURN' - a particularly annoying part for me). It all just seemed too patronising to me, and I felt that the orangutans were portrayed more as participants in a game show in a Big Brother kind of scenario, who's prize was to win a stay on the island than that the aim was actually to rehabilitate the animals. Another part that annoyed me was when the narrator said something in the first episode about how Lona was trying to form a society of Orangutans on the island that could live together (unlike in the wild where they are solitary animals) which had 'NEVER BEEN DONE BEFORE' (another melodramatic phrase)... I was under the impression from Orangutan Diaries, which I have much more trust in the Orangutan Island, that her actual aim was to eventually rehabilitate these animals into the wild, and that the island was their stepping stone to this release... as I recall there wasn't a single mention of this in the first episode. I noticed that two of the orangutans (Cha-Cha and Dianne or something with a D)were described to be fighting and then all of a sudden turned to best friends in a very dramatised part. In fact, I believe that in the first scene where they were 'fighting', they were actually playing in a rough and tumble sort of way often seen in the Orangutan Diaries series, and that this is just another American 'staged for show' story. Overall, I was very disappointed with this purchase, and certainly will not be recommending it. The only redeeming feature was the orangutans themselves who are very special individuals, and this series does show the differences in character and personality well, but everything else was a disaster.
EDIT: I just noticed that another reviewer also compared this program to Big Brother, but in a positive light? Interesting.
