I'm sure long devoted Twin Peaks fans do not want to see more hypothetical threads about the show's potential, but after watching every episode to number 22 (FWWM prequel included) I have noticed some things that if changed probably could have saved the show.
It is my opinion that the shows overwhelmingly large cast at leasy partitially contributed to the show's cancellation. The large cast was essential for the initial Laura Palmer whodunit but once that was solved the focus of the show seemed to set on secondary characters (I consider anyone not closely linked to Laura or the police investigation to be secondary) and the overall theme shifted into what I felt was a kind of mellowdramatic soap opera.
For season 2 I would have focused mainly on BOB & the two lodges and would have phased any non integral characters out of the story save they were "inhabited" by black lodge spirits, which would drive the story further.
I was also a little disappointed with Windom Earle, I strongly believe that he could have been 100% more of an evil genius rather than an eccentric loon. When I first read about the character I thought about a John Cleese or Christopher Lee-esque character who was more elegant than loony toon acting.
