I also just watched this and felt that it's portrayal of JW life was spot on. The only thing is that there was little context and background info, I think, for a non-jw to understand the film.
The really funny thing is when I watched it I had this realization of how actually creepy and weird the JW religion is if you are a person looking at it from the outside. I guess i'm so used to the crazy that it doesn't really phase me. But this film allowed me to be a spectator (and now I'm not a participant obviously) which gives a very unique perspective. Kind of like how it would be if I would walk into a meeting again after 10 years. Very cringy.
