After two fairly vague teaser trailers, we're finally getting a look at the first full trailer for David Fincher's The Social Network, chronicling the rise of the most popular social network in the world. My initital take? Damn, I had no idea it'd be quite this....dark. I'm sure most of that is Fincher's influence. The teasers certainly gave the impression this wasn't going to be a picnic, or a lighthearted take on the story, but this trailer pretty much confirms it. The Social Network is due out on October 1st, 2010. Check out the trailer and let us know what you think.
