Except the only thing anybody will ever remember is, "Joe Schmuck, wasn't he that guy who wrote that goddamn awful script that was torn apart on the web. Yeah, think we'll pass on him."
The whole idea shows a stunning lack of respect for writers, especially those who may not know any better. Why would you ever knowingly put something out there that is bad? Especially when the nature of the review will guarantee it spreads like wildfire throughout the net?
So, no thanks. I won't send you a crappy script so you can have a little sport at my expense ... that's what family and non-film friends are for!
