I had the same thought. Like its friendlier younger sister. I think Twin Peaks fans realised early on the main point of the show wasn't so much who killed Laura Palmer, but the weird and wonderful characters in the place. Northern Exposure doesn't really have a One-eyed Jacks or a Bob... But it does have a Bigfoot character that could be right out of it.
I'm not so sure about that assessment of Twin Peaks. Look at the back half of season 2, where the "weird and wonderful characters" become the focus of the show. It's barely watchable. When Lynch came back for the final episode of that season he refocused it on Laura Palmer and brought back characters that hadn't been seen for many episodes, like Laura's mum or Audrey's brother. They weren't much fun, one being wracke…
I admit I haven't seen it since the original airing. I would likely evaluate it differently now.
