Query: Excellent collection of hard-to-find vintage sci-fi

If you're a fan of this genre, this is an excellent collection of B&W; sci-fi films from the 1950's. The video transfers and the sound are really excellent. And the films are a lot of fun -- as much for what they say about the culture of the 50's as for the stories themselves.My only complaint (and the reason for four stars instead of five) is that the studio skimped on extras; the films don't even have scene-by-scene menus. Given the price of this package, that seems a bit cheap.
