Baltar is somehow of duped into giving the Cylon "female" access to the defense systems just for a roll in the hay? Kinda weak IMHO.

That's not the impression I got. They mentioned that she actually contributed a lot of the program code for the system, as if she were a consultant. And they gave the impression that Baltar was taking credit for her brilliant work. I think that the scenario is that Baltar thought he was taking advantage of her technical expertise, but she was actually taking advantage of him. And he had naively given her access to the defense network so that she could work on it as his "apprentice". The "roll(s) in the hay" was just further playing to his ego and roping him into a false sense of security, making him think that he was the "user", not the "used".

That's a good scenario. Your enemy secretly helps you build your defences and builds himself a back door to shut everything down just when it's needed!

Precisely!

Unfortunately, much of the criticism I'm seeing here belongs under the same heading as that leveled at the first two Matrix movies.

The critics aren't up to the object.

Personally, I can't think of a worse piece of dreck than the original BSG. Any longevity it's had has to be due to the strength of the concept, and the merciful forgetfulness of it's viewers.
