Does not deserve as high of a rating as I've given it, but since I'm a fan of the show, I enjoyed it more than I should have.
By all means, this is a mess. The story has some major issues and inconsistencies with the show, the acting is melodramatic in a way that the show never was, and the film's entire reason for existing is questionable.
However, this movie gives a new layer to the show: a darker, uglier later to the quirky town of Twin Peaks. The question is, was it really necessary?
