Good video, I have seen it a few times and showed it to some of my non JW family.
I believe that a video like this with a bit of humor can be really effective on JWs who are having doubts and researching on the Internet. Using humor is much better than being angry or bitter, which would make JWs turn it off straight away. But if they listen to a video like this and can see the funny side, a small part of them will realize that it is all true, and a few cracks in the wall begin to appear.
I know for me, the funny and sarcastic style videos like this one helped me immensely when I was learning TTATT.
