Hmmmmmmmmmm...
Have you seen any Haneke yet? If not, then you should. Maybe start with...
Caché.
Or maybe some more Bergman.
Fanny & Alexander, in some ways, feels similar to
The Tree of Life. watch the +5 hours version (mini-series in 4 parts). Or
Winter Light if you want something stark (@X) and an existential crisis.
And you should watch
Nymphomaniac (director's cut). Doesn't matter if you haven't watched anything else by Lars von Trier.
