I wouldn't say massive douche but there were a few things that I didn't like about their attitude. But if you go past that the storyline is pretty ok and the movie overall, which features a few other game developers is actually worth watching.

If there were more in-depth documentaries about programmers, you would probably find the same types of personalities reign supreme...emotional, introverted, weird. If you consider yourself "normal" & "emotionally stable", then you probably aren't a very creative programmer.

"A massive douche"? You'll have to explain that one, because I've watched it, and he didn't appear "douchey" to me at all.

Are you sure you're not thinking of Phil Fish? That seems much more likely to me.
