[quote name='zenintrude']Grabbed this... no idea why, but I grabbed it.
The Complete Series is coming out April 26, 2011, so they're probably clearing out for that... for me, one season is probably enough.[/QUOTE]
Actually season 1 is pretty bad. All season 1 deals with is our solar system, the moons, extra. It's rather "bleh". The later seasons go into cool far out things like gamma rays, other dimensions, the multiverse.
