I too have been watching every episode. I'm so proud of Leah Remini and the courage she and the others have shown by speaking out.
Knowledge is power.
Hopefully anyone thinking of joining scientology or any organization (religious or otherwise) will do their research first. In this day and age, most often it just takes googling it.
You may already know there is a good documentary, Truth Be Told, about JW's. Also the movie WORLDS APART is based on the true story of a 17 year old JW who chooses her 'worldly' boyfriend over her religion. It is very well done. It is a foreign film so there are sub-titles. Well worth watching.
