The film would do better if it left all the "Nuclear Boogy Man" flash forward sequences on the cutting room floor.
It's almost like the director or film maker had a agenda to portray Nuclear Technology in a negative way, and wanted to retcon some guilt on Marie Currie herself.
There was potential to do a good film, but its ruined.
Hopefully some other director takes up the task and makes a better film about this most extrodinary person.
