I loved this as a kids and my kids enjoyed it too. The way the family works together is great. The animals cracked my kids up. The fight with the pirates at the end is a little more violent than I normally allow my kids to watch. There is shooting and sword fighting, but on the whole a great family film.
After seeing this movie as a child, the Swiss Family Robinson tree house was my favorite attraction at Disneyland. (Alas, it has since beome Tarzan's tree house.) It's a great adventure film with an unfortunately significant amount of violence. I don't think children under 5 should see it (although I let my son see it at 4.) There is also sexual content: the boys discover that the cabin boy they rescued is actually a girl, then treat her entirely differently thereafter. As an aside, I don't know what Indonesian pirates might have looked like during that time period, but the group portrayed in this movie is a very strange hodge podge of costumes and styles.
I'm always looking for movies that can span the 4 year age gap between my 9 year old daughter and my 5 year old son. This one worked! I'd forgotten what a great adventure movie this is and shot in a beautiful location. There is some violence and a very scary river snake that attacks the Swiss Family Robinson boys, but it didn't send my 5 year old running away. Often the stereotypes in old movies make me cringe and I spend more time explaining how society has changed than enjoying thie movie. This one was easier to stomach than most - acceptable gender roles. There was a somewhat stereotypical portrayal of South Sea pirates, but they were pirates after all. Lots of fun for a lazy Friday night at home.
I wish I had waited a few years for this movie. The pirate attack scene shows pirates being crushed by heavy logs. It wasn't graphic like today's movies, but it was the first time my children watched people being killed. The two older sons fight quite a bit over the girl. Also, while the boys are incredibly industrious, and the eldest son sticks to his convictions on the kind of life he wants to lead, the women sit around in pretty dresses and aren't at all helpful. Better for boys.
