I am a BIG fan of David Lynch, and my personal opinion on how watchable Twin Peaks is today is this: for those who are not fans of the show, you should watch only the episodes directed by David Lynch himself. In other episodes the directors seemed to be trying to follow a very vague overview of what the series plot was supposed to be, like they are just filler. Not much happens in the episodes that air between the David Lynch-directed episodes, as if he wasn't even there when they were writing those.
