The film is a masterpiece. The fact that people would rather have never watched it is due to how well executed it was. Personally, I still enjoy watching it every couple of years.
I mean, Zuckerberg has also been practising martial arts for a while now and has entered competitions. I don't think he's doing it for attention... Once you get the fighting bug, you want to compete more and more to push yourself to be better.
I went and watched it with my missus. We laughed throughout and didn't take it seriously, and there were no intense conversations after. I think I'd re-evaluate my relationship if I were being judged on my reaction to a pretty light-hearted comedy about a doll world.
