The story is fine, it does help make B5 seem more real, etc. But I don't see any real character development, nor any subplot that helps a larger story arc - the reasons why I like B5 so much. I gave it a C. At least it didn't suck like "Grey 17 is missing" or "Infection".
If "Grey 17" was called "Denn'Shar" ("to the death", which was Marcus' challenge to Neroon in defense of Delenn--to me the
real A-story), I think it would be remembered more as an arc episode.
While there's nothing too direct relating to the arc, we do get a good sense of the "flavor" of political trends on Earth with this one: that labor is being particularly devalued (this seems to increase or decrease in historical cycles), government is becoming more inflexible and less receptive to moral appeals (again relatively speaking), anyone without (percieved) power to exert is getting stepped on more, Zento reflects some glaring arrogance of the powers-that-be (no real attempt to negotiate whatsoever), etc.
I like the reference to the Matewan Massacre of the 1920s (although it's pronounced MATE-wan, not MAH-teh-wan as in the ep)--the movie
Matewan about this pivotal labor-struggle event is one of my favorites.
I think Zento's acting was a little overdone, and while he is supposed to come off as very arrogant, I think the flunkie EarthGov would send in that situation would be more of a slick smoke-blowing bullshitter type (well he did try to do a little BSing, but he clearly wasn't very good at it) than an unsubtle heavy-handed ass--but maybe that really does reflect their real level of arrogance.
