All the Titan crap and the OMG BABIEZ angst was godawful.
I would have loved just the Erika Hernandez story as a stand alone, not constantly interrupted by seemingly ever other Trek character ever.
Yes, this was the worst part of the books, Troi had a high risk pregnancy, there was no way I could suspend my disbelief enough to let her be on that away mission. And IMHO the doctor that allowed her to go was a quack. That just didn't work at all for me. I know Mack was trying to give the books tension, and suspense, but he should have found another way.
