Okay, so I also agree that it is hard to conceive of how the producers will keep this alive given the trajectory of this program, but is the program really that bad? The sexuality between characters: were men to take horribly long space engagements it is believable that a level of sexuality might be tolerated; it is human nature after all. Suppress it for 6 years, I think not.
I like this show, and am enjoying it. I can't think of anything better to watch on television, really. My greatest fear is that like the X-Files, it will come to a speeding cataclysm of a wreck, with poor writing and insufficient funds. The problem is not in the drama, or the relationships. The problem is in maintaining Nielsen ratings, where more and more outrageous plot twists are added to attract viewers, which can be fun, but never realistically brought to a coherent conclusion.
I think folks should give this one a chance, but given their short attention, I'm fairly certain they will not. Just keepin' it real, monkeys.
