Wow!!!! JP and I...are in total agreement.
This is a slovenly paced, uneven mess. There is absolutely no character development, and no one...I mean...NO ONE...likable. I tried to like Eduardo. But the only reason he's likable is because of how, conversely, Zuckerberg is such an emotionless asswipe.
There's also nothing to be learned about the actual development of Facebook. Let's not forget that in 2006, Facebook wasn't popular among anyone but college kids. It was MySpace that was the king of the crop. It wasn't until 2008 and after that FB became more popular and I'd say only in the last year has it rose to almost Google-like status. This movie makes it look like FB was the creator and inventor of what we now know as social networking, only making a passing mention of MySpace and Friendster (which I was on, back in 2003--oh and by the way...they had relationship statuses, too, IIRC).
What really drove me nuts was Sorkin's continuous insistence on making every goddamn character have an IQ of over 150. NOBODY TALKS LIKE THIS. Maybe a handful of people...ok. In "The West Wing" it worked. You expect, even in a fantasy White House world, that everyone is smart and quippy. In this realm it doesn't work at all. Everyone's got a get a "This is what the audience is thinking, and I'm going to make it a really clever, snappy line so that everyone will laugh and think it's clever!" line. My prime example is the trophy fish analogy.
I didn't like the casting of Timberlake. Almost every scene he was in, except his last, was basically like "Hi. I'm Justin Timberlake. I'll be playing the part of Sean Parker."
About the facts of Facebook...I think this was probably pretty inaccurate. That's what I've heard anyway. But this isn't my issue. Here's my issue.
Aaron Sorkin wrote:
"I don’t want my fidelity to be to the truth; I want it to be to storytelling," Sorkin told New York magazine. "What is the big deal about accuracy purely for accuracy’s sake, and can we not have the true be the enemy of the good?"
The big deal is that you wrote a BAD SCRIPT, Sorkin. If this is nominated, along with "Inception", for best screenplay, I'm going to do something of extremely hyperbolic suggestiveness.
This movie is not good. It's pandering, dull, and annoying. And it's not even an interesting story because there's no cause of conflict, no resolution, and absolutely no point at all. Except that power can bring greed and blah blah blah...real original.

* The only reason I don't give this an Ohfer is because Andrew Garfield, once again, was very good. And so was Eisenberg, for what it's worth. Their characters weren't well drawn but they were good at their performances. And I had a few chuckles early on. The first 20 minutes of the film were very good. Then it just, as JP said perfectly, "sat there."
