Series 2 did overfocus on the characters, but the eccentric characters were there at the beginning. Log Lady was the most outlandish but Pete Martell and Audrey Horne get introduced early on and are quirky. Dale Cooper himself is pretty strange.
I always thought the most boring major character in Twin Peaks was James Hurley, the would be biker.
I never watched the third series. I think I got part way through the first episode and never bothered with the rest.
