And I noticed the grid-will-get-you-ness of it the last time I saw it, too, which is one of the primary reasons I think it's such a very strong candidate for being turned into one of the increasingly rare good remakes. As I recall, my fantasy cast had Keifer Sutherland as Cody, Helen Mirren as Ma (for the incestuous win), and I wanted to cast Verna with a POC (of hopefully the same stripe as whoever played Cody's undercover nemesis--Vic? I can never remember that rat's name); I also really wanted to ramp up the omnisexual subtext into text, 'cause...um...you can DO that, nowadays. If you're brave enough.
