That's a really good list, Boost. I can't understand why the Old Dark House doesn't get more exposure. I guess because it has no sequels like the Big Names?
It seemed like a big wasted opportunity to not do a few discs like the one you've suggested back when they did the Legacy DVDs. Those had multiple films on each disc in order to have the complete series in each respective collection. Why not make a set or two that covers stand alone films?
(I guess those sets are on BD now... I should upgrade!)
