How much believable is it?

My thought is : Why haven't you suggested any reason I would want to watch it? Because I might believe it, or might not is no reason at all.
 
The for the info. Never heard of it but looks interesting. I noticed there is a site debunking the film.

I also noticed they interview Deepak Chopra. In my opinion he is either a charlatan or a smart idiot and interviewing Chopra devalues the film.
