Don't be a dope and buy this at any retail outlet, even your local DVD-Rama at 3 for $25.
It's available on Amazon, used, for under $2, and about that much for shipping.
It's worth a watch, but not for more than $5 total.
Now you know why I am an advocate of video piracy.
Part of the first season of Showtime's MASTERS OF HORROR, you see the films on the big screen (read: movie theatre) or the new-big screen (read: the $5000 plasma theatre in some rich folks' home-theatre) and, quite possibly, you buy the video when it comes out...BEFORE it's in the special mausoleum-fashioned box set (cheaply made, with absolutely no booklets whatsoever.).
And then it's available for less than $2 on Amazon.
Now THAT'S scary!
