For something that debunks other stories, it's not terribly accurate. The Slotin and Daghlian accidents were not bomb assembly and not "bringing together enough Plutoniom". They were about toying with an almost-critical bomb core and neutron reflecting materials. In both cases, familiarity bred contempt and a minor slip-up caused the thing to go critical. Same casual attitude as "carrying half a critical mass on each side in a lab coat pocket". What if once you forget and hang up the coat with the pieces still in the pockets?
