To understand the Saw series, all you have to do is look at the production company’s logo. Before each film, the words “Twisted Pictures” are ensnared by coils of nasty-looking barbed wire. Then they are impaled by a metal spike. Then the metal spike is rotated, tightening the wire and gouging deep scars in the poor letters. In less than ten seconds, this animation encapsulates the series’s infamous modus operandi: horrible pain is inflicted with low-tech tools, and we’re forced to watch. Twisted.
