Extremely cynical and even CRUEL
From what I hear about the plot for this, it's like these former colleagues and friends of Will Smith's character are going out of their way to make him appear crazy, so he will be sectioned in a loony bin. If I recall, the man has already lost a child and that's why he's writing the letters in the first place, and so his mental health is already poor and fragile as it is. But to hire actors to portray the elements of his letters and interact with him and to have it filmed, and then erase them from the footage so he appears to be insane is really going to push him over the edge! All for corporate and monetary gain, too!
This movie sounds so cynical and cruel to people with mental health issues, that it really is going too far. And the trailer doesn't even reflect this cruel plot! Either Will Smith didn't care or he did it for a quick buck! I hope this crap gets BURIED at the Oscars!
