Quite frankly, a penny under a tenner for these films is remarkable. "The Incredible Shrinking Man" is regarded as a cult classic in its own right and is worth the money on its own IMHO. The other selections are great - from interstellar reaches of This Island Earth, to the swamps of the Black Lagoon and interspersed with fear, monsters, frights and suspense of the other films. And all the films are great for repeated viewing. Obviously, modern day tastes mean the frights aren't as in-your-face, but the subtle use of music and suspense more than makes up for this.
I have to wholeheartedly agree with another reviewer that Them! - with the marvellous giant ants - would have made this a truly majestic boxset. And for that I have taken a star away.
