Watched it with my 74 year old mother. I liked it but thought it ended rather abruptly but I guess that had to do with them just trying to wrap it up and get it out the door.
She knows a little bit about Bitcoin but she said that afterwards she still doesn't think she knows any more about it than before she watched it. She kept asking how the companies in the movie were making money and I think the coverage of Silk Road and the drug dealer made her uneasy, she said afterwards that the movie made bitcoin sound kinda scary (being older and being in that mindset of believing the banks and drug war and all that).
