I first started watching the show in '98, when it was aired on our local Sci-fi themed television station. I must say, it wasn't that bad, and was easy to get caught up in.
The show was done by Gerry Anderson (Thunderbirds, Stingray, etc), but not only did it use the same types of models, it also combined live action, and instead of CG aliens, masks and makeup were used. The concept was different than most shows out there; the idea of a Space Police department, where aliens and humans work together. The "space car" designs were done well. The special effects weren't that great, but they weren't cheesy either. (like Captain Power or Power Rangers)
The idea may seem like something a younger person would find interesting, but with the violence, mild-cursing and adult situations, it was apparent that this was an adult oriented show, almost like NYPD Blue meets Star Trek. The characters were well developed, and the plots kept you wanting to watch, each episode or 2-part saga having its own twists and turns.
All in all, a great show to get attached to. I taped all the episodes, so its a really good show to watch on a lazy Sunday afternoon instead of Golf or auto-racing.
