I did not expect this episode to inspire 9 pages of comments
Basically, I think the episode had a really nice premise. I enjoyed watching (what passes as) a normal day on B5 through the eyes of "the worker caste". Of course they had to meet Sheridan & others - I think it was the whole point: how the 'powers that be' are seen by the regular people.
When I read these 9 pages of pros & cons of the attackers, I could see the merits on both sides' arguments. I think the problem for many was just that for the most part, B5 was uncannily meticulous in drawing loooooooooooong arcs. Cause and effect of the highest quality. This was one of the episodes where there's no foreshadowing of any kind (and yes, I noticed the "Is it them?" etc.) and I can see why that might bother some, and why it might even be deemed a bit unworthy of the general style of B5.
Mack and Bo were nice enough. I guess this was supposed to be a bit of a slapstick episode. However, I just didn't think much of their dialogue that funny... and that's a problem. Tastes like chicken came up way too often. And if the "what is this used for" was supposed to be funny/ironic/whatever, I don't see how. These were the kind of professionals entrusted with fixing CNC tech, and medlab hightech - and what, they were sweeping floors with something they don't know the purpose of (nor seem very interested in understanding)?
As usual, Londo & G'Kar save any episode. I was actually a bit moved watching their scene, them bickering, yes, like an old married couple. 4 episodes of near-murdereous feelings, and this is where they ended up. Just made me happy
All in all, I quite liked this episode but I think it could've been much better. Nothing wrong with the performance of the actors but the comedy writing was lacking.
