Here are some underrated suggestions if you are looking for something to watch.
1. We Need to Talk About Kevin - A psychological thriller about mother - son (odd one) relationship. Its really good and dark.
Imdb Page for more info.
2. The Man from Nowhere (Ajeossi) - A man with a violent and mysterious past dives into trouble because of his neighbor and her little daughter.
Ajeossi (the name of the movie) means "mister" in Korean. If you watch it in original language you will hear little girl calling that a lot. :)
This is one of my favourite action movies.
3. Kahaani - It's about a pregnant woman searching for her missing husband. Indian movies are usually absurdly rated in Imdb (Indians no offence =)) but i can vouch for this one.
I hope you enjoy all.
