A documentary of what exactly? This "movie" is boring, annoying and completely plotless. The only given narrative is of a juvenile story about a big fish roaming the oceans and they look for him all over the world's tourist attractions (even when it's not near the ocean).
The main themes here are:
- Watch how beautiful people walk topless everywhere, which is sometimes extremely inconsiderate of local people (on a bus in Nepal??!!).
- Watch how these beautiful people have beautiful children.
- Watch how these beautiful people embark on a "great adventure", which is basically flying all over the world and go to the most touristy places.
- Watch how a hippie father teaches his son to treat animals solely as food and hunting practice.
- Watch extremely well-shot surfing and nature scenes - basically the only reason to switch from seeing the trailer to watching the movie (and the disappointment that follows).
