Very disappointing. Well, I have to disagree with those saying it gets better. I watched all 10 episodes (presumably because I haven't yet fully accepted my own mortality or that one day i'll be on my deathbed and pretty keen to have those 8 ish hours back) and for me it didn't, though it did at least get unintentionally funny at times, which is something I guess. Among other things the big, scary black cloud of literally _dark_ matter made me laugh - you have to at least admire the sheer cheek of a sci-fi writer that apparently can't even be bothered to read the Wikipedia entry for the science they reference.
Most of the characters are petty, unlikable and stupid (and not stupid by "best and brightest" standards, stupid by average high-schooler standards - like, shout at the TV, pre-'Scream' horror movie levels of stupid). Which I can accept if they're at least interesting but almost without exception this group are interchangeable cliches that we never get to know on anything beyond a superficial level. We don't like them, we don't respect them and therefore we don't root for them. The plot is also nothing we haven't seen before. It plays out like a 50s B-movie but without the schlocky charm or self-awareness.
If this somehow gets renewed I certainly won't be watching any more, not even for Katee Sackhoff (hard not to view her character running around trying to hold the ship and crew together despite their incompetence as a metaphor for Sackhoff herself trying to hold the show together despite the writing). By the end of season 1 it didn't feel like a show finding its feet, it just felt like one that, given the chance, is capable of finding all new ways to be terrible.
Still, 3 stars split between the ever reliable Sackhoff, the attractiveness of the cast and as consolation to the many people involved who were no doubt at least _trying_ to make something good.
