Mother (2009)
Directed by Boong Joon-Ho (directer of Snowpiercer)
I recently watched this film and I enjoyed how the the film not only had an interesting plot, but also how the characters were very well crafted by the filmmakers. I found myself intrigued by each of the characters and the stories behind them. This film made me realise that sometime characters can be as strong as the plot itself. It also features a style of cinematography I really enjoy.
Here is the trailer:
