The editing, humor and weirdness of this movie carried it all the way for me. If it has been just one ounce more realistic it wouldn't have been worth it, but it tiptoed through the entire movie with a main character that was a real ass and with archetype villains that was predictable but yet funny and a nice touch in the "storyline" where you follow a meeting where the main character is getting sued and at the same time there's "flashbacks" to when the situation escalated.
Any way, the movie is also quite interesting in the sense that it is based on a real story. I went through the Wikipedia article on Facebook afterwards, and most of the facts are the real deal, then I guess the interaction between the relevant parts has been tampered with a bit, to make it more… movie-friendly.
