The Doctor (very good character and mostly due I think to the talent of the actor Robert Picardo)
Seven: She started as a Borg babe and turned out to be a very good actress, much better than the lackluster (Harry Kim) who definitely should have been the one let go instead of Kes.
The stories were varied and ambitious, if sometimes idiotic (but we're not here to talk about that).
Just saying, this doesn't sound particularly positive to me. It sounds like the same old rhetoric that's been said over and over and over. So, allow me.
Kes was a
terrible character. She brought nothing to the ensemble, she brought nothing to the show. Episodes that feature her are among my least favorites. Part of the problem is she looks like a little elfin boy, and the other problem is, Jennifer Lein can't act. Or, at least she brought nothing to that character.
Harry was boring because the "naive young ensign" shtick got tiresome quickly, and that's all the character ever was. And, Garett Wang wasn't a good choice to play that type of character, anyway. He appeared "too old and experienced" from the first episode. That being said, the character at least had a place in the ensemble.
What was good in the show?
First, they realized that they needed a strong, "mysterious" character to add some manageable tension and conflict, that wouldn't get old. And they added Seven. Seven was the "Spock" or "Data" character. She was intelligent and conflicted with her own self as they both were. Just like Spock and Data, there was plenty of room for her to conquer that inner conflict, and grow as a person. It was the absolute right thing to do. There is no way Kes could have brought this to that show.
Second, this was the only incarnation of Star Trek that stayed close to the spirit of TOS. TNG was a cruise ship in space, complete with it's own armchair psychologist. DS9 certainly didn't. Janeway was a strong captain that was not afraid to be the captain. They also boldly went where no man had gone before.
Third, Robert Picardo was perfectly cast. My favorite ST doctor.
I'm tired of hearing how boring Harry was or Tom, or Chakotay was. Because I think people forget that on TOS, Chekov was boring, Sulu was boring, Nurse Chapel was boring, Scotty was boring, and the entire show was Kirk and Spock with a dash of McCoy, who was somewhat boring too. I certainly think Tom and Harry were better characters than Chekov and Sulu. On TNG The doctor was so boring they tried to get rid of her, some nutcase usenet fans hated Wesley Crusher so bad they pretty much drove the character off the show and hated on the actor to the point of nervous breakdown. Levar Burton was OK as long as he didn't have to try to act beyond the 5 or 6 lines he repeated every episode, and please explain Tasha Yar to me. Thank God for Worf. Half of the DS9 ensemble is just unlikable, forget boring. Again, thank God for Worf.
The point is, we see what we like with rose colored glasses, and hate on the rest. But it's virtually all the same. It really is. Except maybe Enterprise. They tried to do something different there.
