One thing that I would have liked in the show was reaction shots from the various other characters in the saga. For instance several times during the series after major turning points I would have loved a cameo of the Enterprise with Picard and crew commenting on say Betazed being captured or Earth being attacked. Also it was a shame that Kai Wynn didn't have an appearance while the station was occupied in season 6.
It might be asking too much, but for me the crew of the Enterprise was the heroes and everyone else was great, but I just wanted them to play a part.
