I know nothing of the in's and out's of the licensing agreement to Troll2. Acknowledging that remaking content will mean one less new Riff will be made, so this may be more hassle then it's worth but...
I'd really like to see Troll2 get the "Three Riffers Edition" treatment. My opinion is this is as important a movie for fans of Rifftracks as Plan 9 From Outer Space and arguably more important then some of the films that have been done twice.
