Through A Glass Darkly (1961)
One day in the life of Karin, a young woman suffering from Schizophrenia who goes to visit her father and brother at their island home. Initially she is symptom free after taking some medication but as the injection wears off, her condition slowly unravels her mind.
Really quite enjoyed this... Harriet Andersson was/is a terrific actress.
500 Days of Summer (2009)
A man working at a greeting card writer's office falls for the new receptionist Summer. The film plays out their 500 day relationship. Sometimes it's going fine, other times it's a disaster.
Thought this was gonna end in a bullshit happy ending. Surprised....Kinda.
