Very good movie overall. The story is very interesting and important, definitely a must see to realize from how far we've come as humanity and that it has taken us a very long time to get here.
The shots are beautiful too, almost photogenic. It shows the countryside of Italy. A part we most of the times don't see in the big budget movies.
The only thing I wanted was a longer, detailed movie. More in depth on the characters, as I had the feeling that is what needed to tell a story of this magnitude.
Overall a very decent movie which I would've given a 7,5 if IMDb let me. I hope this film gets more exposure than it is getting right now.
