I will admit that I am an Adrian Paul fan. I also love Science Fiction in books, film, and television. While this show may not be unique in idea, it does bring new things that haven't been utilized in other shows of its type.
Tracker starts out sort of rough, and doesn't answer many questions. But if you stick with it, those questions do get answered. Each episode explores Cole and Zin a little bit more than the week before.
The actors work well together. We all would love to see a show that feels like it is in its third season when it has really only just begun. Many television shows don't start out all that great, but then come into their own as they grow together as a cast and the story starts to unfold.
Give Tracker a shot. There are funny moments and great effects.
