Well, I feel stupid for having seen it. It doesn't describe OCEAN, g factor or other scientific things. It just follows this guy for a few weeks and he thinks meditation helped him get more happy, temporarily at least. This is not about personality and this is not that scientific. Yes, certain things make us happy. But epigenetics and genes is one thing - test it god dammit, because this part was actually interesting! He just talks about it but never even tests himself besides a on a small happiness scale. Also, it is way too flashy and tries to be cool - which makes the whole show seem less serious.
A let down unless you want a feel good story.
