Outside of saying I think Shindig is my favorite of the first four episodes, I don't have much to add. I really love the entire episode from the ballroom scene to the swordplay where Mal pokes and jabs the defeated Atherton.
This episode really highlights the Companion's place in culture and society. I think only the movie "Serenity" and, possibly, the episode "Jaynestown" help further our understanding of Companions.
Loved the removable doorknob and the floating chandelier. The holo pool balls were the best!
