The movie was fascinating as was Heyerdahl's book. The problem is the "extra" material - an interview with Thor Heyerdahl and extra film clips of the Ra I, RaII and Tigris expeditions. Any first year film student could have done better. There were almost no captions or identifiers, the interview was chopped up and interspersed with clips with no explanation or relevance. The whole looked like a hasty mishmash that should never have been released. The extra color footage was fine. The extra on the "crew" could have benefited from a bit more than the name. As Heyerdahl died in 2002, that would also have been useful information. The photos -- with captions from the book -- were fine, if only the "interview" extra had been done half as well.
