Sadly... you can't get it locally here. And even if can get the imported version locally here, it will be very expensive (I believe the 1st season would be RM 500++; 6 DVDs with a companion).
Unless you try to get The Twilight Zone Collection... which has 9 DVDs each set (in 5 sets to complete all 5 seasons), all the episodes are randomly inserted.
I prefer the Definitive Edition because there are extras you don't get to see (like those sponsored commercials... and next episodes). If you get it from Amazon, you pay RM 400 more or less (excluding shipping).
Well, I am currently watching the 2002 The Twilight Zone series where Forrest Whitaker was the host. Some of the episodes are good, some are bad, some are cheesy, some are sad. Still, since I'm a big fan on collection The Twilight Zone... I might as well get them all...
