1st few episodes were pretty good then the show started doing irrational things, the decisions and plot it had built up by episode 3, all of a sudden the show started changing in episodes 4, 5 and 6. Some of the characters are pretty annoying and its unrealistic the flippant nature they have when they're supposedly super trained for emergencies and their mission and the serious nature of their predicament. I guess the show can't be too serious and realistic or then it wouldn't be "family-friendly" and fun. I guess it's good family fun with enough interjected comedy and people flirting and such. But for any sci-fi fans, its lacking and quite disappointing. I am probably not going to end up finishing season 1.
