I thought it was a great movie. The acting and dialogue were great, and Trent Rezners music for the movie oddly went perfect with the movie. I think it was that music and direction that gave it that erie feel(the first scene and the scene near the end with the shares stand out)
Going in I didn't think I would like it, but walking out I actually wanted to see it again, and soon. I would definitely recommend, even though it's about facebook, it makes it in a way where the actual facebook is kind of unimportant.

One of the final scenes where Eduardo finds out his shares were reduced was so erie and done so perfectly. That and the first scene where Mark is talking to his girlfriend are the two stand out scenes from the movie, the dialogue in the first scene is just flawless and I think really shows the character of Zuckerberg and how he is, which really helps set up the movie. Did I mention I walked out of this movie loving it?
