Yeah, and the aliens sucked their brains out. I agree, it was freaky stuff-- but, you couldn't have made a every week show out of it, you know? The bugs would get boring.
One of the writers for the old Star Trek show was Harlan Ellison, the fella that wrote "City on the Edge of Froever", where Bones gets hopped up on a hypop-drug, and wigs out and goes back intime to see Joan Collins. Some freaky stuff. I remember that to this day. Harlan Ellison is still around, and he's mentally ill. That's what you need- a good writer that you have to keep locked up in a cage.
The episodes showcase a lot of moral and material waste. There's really nothing to be gained from them other than the impression you can be light years away from earth, marooned, helpless and wanting and you can still get by being a sappy, self-centered, ignoramous. This is probably what the writers figure their audience is.
Consider BSG: they're adrift in space, the last of humanity (supposedly), vulnerable and with limited supplies. They should be thinking of 2 things strategically: hiding and acquiring resources. And the whole 'inter-stellar socialism' theme that runs rampant through the plots is disgusting.
I watch the shows via DVD or file share and usually end viewing sessions with more disbelief than anything. The technological fantasy is interesting but the stories and character actions are a joke. It's Science Socialism.
