Dekalog
There is nothing else out of everything I have watched that is quite like Dekalog. The greatest part is that many people may believe that this was made just for Christians due to the biblical allusion. But the concept is, rather than to convert people, to try reflect on how simply basic morals are broken in modern day life, this being blatant in how all episodes take place in the same apartment complex. If I had to rank the Dekalog episodes, this would be it:
1. Dekalog V
2. Dekalog VI
3. Dekalog I
4. Dekalog X
5. Dekalog III
6. Dekalog VII
7. Dekalog IX
8. Dekalog IV
9. Dekalog VIII
10. Dekalog II
And this doesn't mean that these films aren't all tremendous, because they are. Masterpiece!
