I watched it too, and I have to admit, it wasn't bad at all (in my opinion). I don't watch that much TV lately, so it's nice to have something to look forward to.
At first I thought they were rushing the plot, but all the ingredients in the story are making it quite riveting.
(Okay, maybe there was a little cheese factor here and there ... like, "Dude, we're going on a space ship! That's so cool!")
