Very much in agreement, particularly about Ganz. In the first few books he came across as a dangerous, intelligent character of his own. After the revelation of who was really in charge he started being portrayed more and more as impulsive and cartoonish. It was a disappointment.
Almost as big a disappointment is the tratment of Quinn. He became this action hero just long enough to get rid of Zett and have an adventure and then he's right back where he started. Even lower than that since he doesn't even have a ship at this point. It was a very big swing one way and then even further back and it just doesn't feel right. If he swings back the other was in the final novel it's going to feel even stranger. he was a great character and I'm disappointed in how he's turned out these past couple of books.
Penningtons comment about "the bloody end" may just refer to the station itself. Such a shame that a series with so much potential is being ended.
