I think the stand alone episodes are a little underrated in this thread. Most of them contain a lot of important philosophic topics and show the various alien cultures in much more detail, making them more realistic and believable.
Which would be fine if the episodes didn't find a way to cock things up somehow. I'm not opposed to standalone storytelling, I'm a fan of Star Trek after all, but I just don't think that the standalone episodes of this show are very good.
Believers was very good, but other than that they've been mostly disappointing for me. Example:
Knives (*)
The Babylon Triangle? I have not heard of this before. I'm betting it's stupid. Oh look, a dead alien. And now the dead alien has grabbed Sheridan's face. Clearly Sheridan is now possessed by some sort of alien, I hope this episode doesn't drag on and pretend this is some sort of mystery. Oh look, Sheridan is seeing patterns which aren't there. That's a sure sign of being possessed by an alien. Now Sheridan sees some sort of monster that's not there. Another sure sign of an alien. Now Sheridan is seeing his wife's ship blow up real good. Alien. Now Sheridan sees a vision of his parents. I'm beginning to think that the big reveal in this episode is that Sheridan
isn't possessed by an alien. Wait, no, he was possessed by an alien, and Dr Franklin is shocked by this revelation. Shocked I tell you! These guys needs to watch more Star Trek, they would have seen the alien coming a mile off.
Meanwhile, with Londo... This story got off to a slow start, and I'm angry at it for pulling that whole "I'm going to kill you, Londo, with this knife, but I'm going to wait two minutes for the credits to roll and then I'm going to reveal that I'm not really going to kill you" thing. But it did become sort of interesting in the middle as Londo began to learn the truth about the conspiracy he is involved in with Lord Refa, this episode has a chance to do something worthwhile yet!
LONDO: I sorted out that issue for you, my dear friend, by talking with Lord Refa, who also happens to be my dear friend.
URZA: Not Refa! He is my dear enemy and is trying to have me killed and stuff.
Oh, a falling out. I like this.
URZA: *throws sword onto table*
Oh no, please don't challenge him to a fight to the death!
Please don't be a fight to the death.
Huh?

That had better not be a fight to the death.
URZA: A fight to the death!
Balls!
Are Western human civilisations the only ones where fights to the death are illegal?
Is there some sort of rule that important episodes have to be followed by Lawrence G DiTillio episodes? Because I'm beginning to notice a pattern here.
