I don't recognize a single one of your bullet points as being about my experience of the movie. The whole conceit was that a brilliant technical expert's unexpected success pushes him into a world he is not emotionally or socially prepared to handle, and ultimately his arrogance and hubris leaves him alone and unhappy as he pushes away the people in his life one by one, ending SPOILER ALERT
beautifully with him quietly desperately refreshing his ex's facebook page alone, starting to recognize how much he regrets everything that he has lost in his pursuit for wealth and power...
Most of the movie isn't about college, or sex, or booze. If you had to could you have broken a site from that era in 2 hours? I'd be shocked if you couldn't. Lots of these sites would die when they get a little too much traffic. Some sites still do today. Security was an afterthought back then. Zuck had a girlfriend, and his friends do just fine. The lawyers are dealing with so much wealth and power in the hands of people who are so young and emotionally immature and they handle it exactly how I'd expect them to.
Zuck in the movie is driven by a lust for wealth and power, which is a universal theme in basically every story in human history.
