I kind of got that about DS9, but I didn't really have a consistent enough schedule to catch every episode. I heard that Babylon 5 had an excellent story if you followed the show, and I may check that one out when I finish getting all of TNG DVD's.

As for Voyager, I saw a couple of episodes I liked, I just couldn't stand Janeway. Star Trek in general has difficulty writing strong women characters, and Janeway was one of the worst. I liked 7 of 9, but people never take me seriously that I thought she was an interesting character (they tend to emphasise other things). Janeway killed it for me though, no matter what the other characters or plot were like.
