Although I would be slightly inclined to agree with kranav's comment, I still feel that the History Channel did a fairly good job delving into this topic as it is very controversial. To be quite honest, I was hoping it would be longer than it was.
There is always one person saying "I can predict the next 500 years and I'm sure we'll be able to match an event up with at least on my predictions", the different is, Nostradamus has accurate predictions. Although his method with his drawings may seem ambiguous to some, there can only be so much that they can define. If someone is able to match up an event that has taken place or and event that will take place with his Quatrains then the only thing you can really do is consider it a possibility. All I can say is, be open to the possibilities when watching this movie and don't think that Dec 21st 2012 will be the end of the world as it can also be start of a new beginning.
