Hmm Firefly. I'm not really into space westerns, but I see it is popular enough for them to make a movie (yet at the same time not popular enough to last longer than one season

). I looked at the trailer and it looks better. Two parts in particular, the fleets and the captains response when the other guys says he comes unarmed
Edit: sorry to seemingly make this all about firefly, but I'm pedantic as all hell and couldn't get past the opening bit about mankind finding a system with hundreds of planets. yeah ok so I know they must mean sector or region but every time I hear it I think "gee some aliens must have been heavily into terraforming to place hundreds of planets in the one solar system
