A good story well acted but spoilt by the gratuitous excess of over loud, irrelevant sound effects and loud, poorly selected music accompanying dialog that only detracted from the power of the script.
The whole soundtrack could be reworked to make this a more successful product and the overlong production could usefully be cut by half an hour or so.
An epilog to tell us how Openheimer live his latter years would have concluded the story, even a closing screen with text would have helped.
