My concern about buying this dvd was where the description says "..Import, English audio". What surprises did that hide? Well, I took a punt and there are two minor things about the item being an import. 1) The blurb on the case is in (I think) Dutch, and there is nothing you can do about that. 2) It is the original English soundtrack but if you go straight in to play mode the dvd will display subtitles (again, Dutch, I think). However, it is not too difficult to find the "subtitles off" option before playing the movie(even with zero knowledge of Dutch). Having removed the subtitles you have good quality images and sound to enjoy.
As regards the movie, which I first saw at the cinema back in the fifties, The Blob has an enduring cult sci fi B movie appeal and I really enjoyed seeing it again. After all this time however I could not overcome the feeling it was like an episode from Happy Days plus a monster. Cue the Fonz emerging from an alley with a sister on each arm asking everyone to keep the noise down. When it is pointed out The Blob has wrapped itself around the Diner with Richie (McQueen)trapped inside, Fonz walks across, points his comb and says "Heyyyy".
