I remember when you had to buy this as a VHS froma dodgy man in Australia. This is the TV show that did not get enough seasons, much like Firefly. It's unique style and not to mention realistic feel made it a pure joy to watch. The series had some flaws, but a wonderful cast and interesting characters, from bad-boy Hawkes to goodie Wang (who kind of always reminds me of Harry Kim from Star Trek Voyager), it is a joy to behold. If you like sci-fi, or even military stuff, this is the TV series to invest your money in. You will love the characters, the storylines...and hey, it's only one series, so once you've bought it, you don't have to buy another. The negative side of this is the lack of extras, but with the show being so old, don't expect any.
