I feel i must reply to the most recent review of this calling it totally unimaginative. Personally i felt that this version of the book was a good adaptation and original in the fact that it was set out over 30 episodes (by the way all 30 episodes are featured on the DVD albeit there are 10 parts with each set over 3 25 minute episodes. Okay lets get one thing very clear this wasn't ever going to win an EMMY but then its aimed at a family TV audience. While i accept some of the accents are poor especially the Children's accents i don't think the acting is any worse than some of the stuff that is produced in North America some of the TV movies produced there are awful. In many respects it was interesting to find out how a family used to the comforts of civilisation would cope if they became marooned on a desert island and while it is unlikely that in a real situation they would come across all the things that happen to them it is still good viewing and i feel that Richard Thomas gives a good performance as David Thomas as does Margo Gunn as his wife Elizabeth and the chemistry between them seems genuine. There are also good performances from Charlotte Woolams as Joanna and Gareth Howells as Ben. While KC Kelly and Jeffrey Thomas ham it up as the villains of the piece.
I have watched this on DVD a number of times and i still enjoy watching it and while some may find it slightly naive it does teach us the importance of family and working together when the going gets tough in order to survive.
