1. Trusting Someone You've Known For Five Minutes
This really goes into real life, but it's something true. Trusting Sean after knowing him for a meal. Every girl in the world will tell you that you can't trust a guy that easily, you have to make him work for it, gosh darn it! Unfortunately, Mark missed the memo about dating a guy (he was basically dating Sean in the movie), and trusted him fully, and granted, yes, Sean put him on two continents, but he let him down completely after fighting for Sean against Eduardo. After everything he did to trust Sean, he was let down. Again, is it something he did maliciously that was highly questionable? No. Maybe more like highly questionable -- but you didn't know better. Either way, I felt bad for Mark by the end. I think we all did.
The Social Network is such a difficult movie because I have listed 10 Highly Questionable things that Mark has done, but I don't believe he was a bad person. I don't believe he meant to do any of those things and make anyone feel bad. He was just going either in his own misguided direction of what was right, or was going under what someone else was telling him to do. Obviously this article missed the big things, did he steal the idea from the Winklevi? Diluting Eduardo's shares down. I just didn't want to get into anything that may or may not have happened in real life. So yeah, in the comments there's gonna be a lot of YOU MISSED SO MANY POINTS! I know I did. But that's part of the movie. He was 19 at the time about to run a multimillion dollar corporation. Did you know what you were doing at 19 or 20? Could you have run something like Facebook perfectly?
