This is one of the better shows out there. It deals with racism in a really positive way and isn't "preachy" or "cuddly". There are a few problems (Why would people who dissolve in salt water choose to live in a coastal city like Los Angeles?) but those are easily overlooked.
The show is really well done and makes some great references to todays society. The new race has drug and alcohol addictions, faces discrimination both inside and outside their communities, and struggles to integrate itself into the human world.
One of the ongoing jokes in the series is the newcomer names. They never had names on the ship so they are assigned names by a human agency. A lot of them are comical, like "San Francisco" but some of them are politically incorrect, like calling a mentally challenged newcomer "Albert F---ing Einstein". The middle name was dropped for the series but the character remains.
I recommend it, it is a great show.
