I like it so far...
Its a lot of things actually,after all its Seth McFarland.
There is humor but they also tackle serious stuff.
This last episode I watched had more moral/societal/religious/global warming/legal issues than Vogue.
The basic was, one form of alien that inhabits their planet are all males in relationships (sexuality issues) and if the offspring (the aliens lay eggs) are born female they are given a sex change operation(gender issues/mutilation) at birth.
Through the whole episode they (male aliens) keep reciting passages from their great book (bible/religion) and come to find out that the their bible was written by a female alien that the parents hid from the masses of males(oh $hit moment).
The doctor of the human occupied ship refused to perform the operation (moral issues) and so the alien male couple went to court(legal matters) against each other to decide the fate of the alien child. This is where they learned who wrote their bible, but the jury was all males from said planet, so you know how that turned out despite all the emotional baggage they brought into the court.
All through this they made the male dominated planet out to be polluted/dirty/blowing $hit up/rude/crude/inconsiderate/crotch scratching mentality and so on.
Is it the most amazing show ever...not hardly but it has some cool twists (Seth McFarland style) some twisted one liners and spoof action mixed in with what he believes to be real world issues.
