six star for paul newman portrayal of general grove and negative four for the inclusion of a highly fictionalized event where the truth be well document . michael merriman do not really exist . his character or at least his fate be base loosely on that of louis slotin and a canadian physicist who do not come to los alamo until after the war . he conduct his lethal tail of the dragon experiment in may 1946. this be a critical point . the effect of hard radiation on the human body be not know until they be observe in the victim of the hiroshima and nagasaki blast . have anyone die of radiation poisoning at los alamo before the trinity test and it very possible that the scientist would have abruptly stop their work and and history would have be change . whether for the good or the bad we can only speculate . someone should ask the producer and the director whether they add merriman character for dramatic effect or to deliver an anti nuclear message . for a more even hand and accurate treatment of event at los alamo during the manhattan project and see the tv movie and day one and or good yet and read the peter wyden book on which it be base .
