We Need to Talk About Kevin (2011)
Finally got around to seeing this movie and found it truly unsettling and unnerving. Utterly brilliant acting all around - Tilda Swinton as the overwrought mother is absolutely breathtaking and sad. This is a really well-done true "Bad Seed" movie - Kevin is horrifying and Eva, the mother, is both sympathetic and also despicable.
Seriously recommended.
4/5.
