Ok, just came back from watching it and have to say, definitely the best movie I have watched for a long time. Acting was great, you saw the side of every character, it was written quite well and even though Zuckerberg was a colossal douche as Oz said, you had fun when he was wailing on the lawyers and others.

My favorite was:

Spoiler

Lawyer :You gave him 1000 $.
Eduardo:yes
Lawyer : then you gave him 18000 dollar
Eduardo:yes
Lawyer : so it means 19 000$ in total
Zuckerberg: wait! *he scribbles on a notepad* yes, I calculated the same amount

or something along those lines, am translating from memory

I would definitely recommend it, a worthy movie experience
