And you might still miss some things the first time but it makes rewatches even better. I rarely feel the desire to rewatch shows, even good ones, Deadwood is the exception.
Hell even the set is amazing because the background extras took their roles so seriously, listening to the commentary tracks the lead actors noted that the background extras/actors developed their own routines and really made the camp come to life.
It had more of a living history museum or renaissance fair vibe than that of a stale set. Everyone invovled with the project had passion for their role no matter how small.
