Twin Peaks is still really unlike anything that's been made since. You'd want to compare it to a show like Psych or Monk or something, a quirky/funny type of show that fosters an insular fanbase, kind of inaccessible in a 'pick it up anywhere' kind of way, but its not. Twin Peaks was never a monster/case of the week thing, and it delves into the paranormal, it goes funny, it goes absurd, but it also has painfully touching dramatic moments of human suffering. And I don't mean like...saw, but like, human moments where you have actual sympathy for the characters on stage.
And of course everything is crisply written, dialogue is amazing, and you really can't blink or you'll miss something you'll realize later was blatant foreshadowing.
At least that's how I remember watching it years ago. It's getting a new season on showtime in 2016.
