The premise is interesting, though I've seen this idea before. The first episode wasn't very good because of poor acting. But we've continued to watch it (finished 4 episodes so far) and I have say it's both growing on me and the acting is better - most of the actors are growing into their characters and becoming more believable, and evoking my own emotions such as finding some likeable, some irritating. I was glued to my seat during episode 3 and worried about what was going to happen next. The crew seems to be in one crisis after another, which can be tiresome as a continuous plot device. I am being entertained now, though I can't give it more than a 6 at this point.
