Yeah, it's a good trailer.
I wish I could say the same for the show. It doesn't know if it wants to be a comedy or a drama.
I'm far from cynical; I'm usually positive about new shows, and give them every chance I can, but the plots are unoriginal, as are the characters. They're stolen from old shows and added a quick coat of paint.
I'm getting the strong feeling this is a vanity project: MacFarlane exercising wish-fulfillment by replaying Star Trek episodes with himself as lead.
GalaxyQuest managed to do this successfully, because it didn't shy from the fact that it was a direct parody (in fact, that was its central theme).
I wish producers had either taken more control, to make it what it could have been, or let go Seth's reins and see what he could do.
