Certainly the best thing I have ever watched on television. Twin Peaks is funny, scary, exciting, the characters are consistently engaging, the music's haunting, the writing's incredible, and half the time you watch, your eyes glued to the screen as you shout 'what????'. The first series is probably better - a far more compact affair, whereas the second season (which has attracted a huge amount of largely unfair criticism) is longer and does begin to tail off at points, leaving you with the impression that the writers aren't sure what to do. But even then, it's nothing but watchable. Even when the storylines become a bit silly, the show itself is so beautiful, the sheer madness of it so engaging that it doesn't matter. Great show. One of the best you'll find.
