This movies contains many detailes. You really need to focus to obsorve all the importent stuff.
There is nothing new about some rich people look down on poor people.However in this movie it is ullustered in a different way. After i finished the movie it made me speechless and shocked. There is a lot of symbolism in this movies. So, focus focus focus otherwise you will miss some improtent topics.

There is a few bloody scenes and I personally is not a fan of it... so thats the reason why I am not rewatching it.

Give this movie a try if you want something that will distract you from the real world.
