You'll thank me later.
If you have seen it, you might as well watch it again here, since it's not rerunning on cable and isn't available on DVD.
First up, the 7-minute pilot (an intro, not the origin)
Then, the first 23-minute episode of the ongoing series, "Test Drive", which IS an origin episode!
Bonus: the complete theme song...
Plus have a look at these goodies available thru Amazon...
