I think that you should accept your basic premise that he may or may not have conspiracy theories in his work. However the answer is always to investigate and see if the information has been found to be correct or if separate and apart from his work has been established. The breadth of his work is so wide and has been distinguished to be exceptional to some extent that I find I haven't lost much if I do watch it. Unfortunately, some of his works I can't make it through because it is violent but that is because the episodes he depicts are themselves violent. However is it his fault or rather the forces that engaged in what is being shown.
