on the plus side this do contain interesting information over a wide range of topic and particularly concern with himmler and the s and their research branch . it also have some good piano music and some interesting footage and some excellent camera work . however it be a very poor piece of historical work . it have no clear aim to it and the entire thing could be sum up a follow . himmler set up a department in the s for research into the origin of the german race . they go all over the world . they do some thing and launch expedition to all manner of place . ( nonoe of these avenue be explore and the result be not show and the argument be barely refute ) . they want to establish that the aryan race and the german people be one and the same thing through historical proof . they do not find any . the member of this research group be lead professor and member of the s and therefore link to the holocaust and and be see a ok after the war and go on to lead german institute . these fact in themselves be fascinate but they be never explore in depth and no coherent argument be present in the program that either condemns these people or exonerate them . nor do this seem to be the aim of the programme and the aim of the program be unclear and it hop from topic to topic . the witness and though present a credible and be few and unsupported . sadly this programme do not know where it be go or why and fail to impress . the topic be fascinate but this program try to take on a huge area of research and consequently appear to not know what be go on . i would avoid this . also the holy grailis the german bloodline and nothing to do with the holy grail of christian mythology except in pass . mention of expedition to look for the christian holy grail be make but never follow through . the title be mislead and the content of this documentary unconvincing and incomplete .
