Thank you so much for your comment and suggestion. I love this type of movies for the same reason, they give you so much more than just entertainment. They give a reason to think about life in general and actually enjoy it afterwards too! If you like movies like that, you def should watch Mr. Nobody :)

That's a really good list. I watched Memento and City of God. Shutter Island's been on my watchlist for ages and I feel ashamed for not having watched it yet! I will watch it soon for sure. :)
