Really fun film for money geeks
I really enjoyed The Big Short (called 'Money Shot' in Japanese -oh myyyy!).
It's not particularly practical (the characters in the film are unusually insightful hedge fund managers, so light years away from your average amateur investor) but it's engrossing, informative, and enjoyable.
Some swearing and a bit of financial jargon, but if you're okay with those very much recommended.
