These rules are simple, and, frankly, will make the whole “Special Edition” more enjoyable. Follow them closely.
Sip if there’s a small change in an established scene
Take a drink whenever Darth Vader’s lines have been changed
Take a drink if there’s really shitty CGI that sure didn’t age well past 2003
Finish your drink if there’s a new or extended scene
If a character from the old films has been replaced with a new actor from the later films, chug until the image no longer burns in your retinas.
