The premise of the show is pretty retarded IMO
If you think nuts in costume are inherently implausible you've obviously never seen footage of a Klan rally or attended an SF convention. And apart from that, what was silly or implausible or whatever the objection is about the episode?
And then thinking about the logic of the episode makes me cringe. Ok, the guy has PST- for 10 years? Has he been thinking he's King Arthur the whole time? If so, he's galavanting about the galaxy picking fights with people and ranting like a lunatic and nobody stops or kills him or puts him away? Or did it just suddenly pop up recently. Can that happen?
And then he recognises Marcus' British accent, which of course sounds nothing like a British accent would have in King Arthur's time. So the guy is an obsessed Arthur fan but wouldn't know that?
Some amusing aspects, some good acting, some nice character moments, but not much by way of story arc - this episode is OK, yet not a favourite of mine.
Michael York does very well in his role. I can't help but wonder who was represented by the dream knight who stabbed him in the back?
Marcus has the best lines: "I take great comfort in the hostility and general unfairness of the universe." Also "Better the illusions that exalt us..."
Dr Franklin is again playing God, forcing a healing for which the patient is not yet ready. The fact that it turns out well doesn't justify that decision, imo.
Interesting parallels between the Minbari war and King Arthur's battles...
Delenn as the Lady of the Lake, Kosh as Merlin, etc. - interesting parallels as well.
Oh, and contrary to my previously expressed thoughts, G'Kar does resort to violence again in this episode...
