Initially, the murderer of Laura Palmer was never meant to be revealed, and perhaps it would have been best for the series if things went this way. However, it is extremely fortunate that this reveal was executed with such perfection and blood curdling horror, making it hard for me to really complain about Lynch and Frost's reluctant decision to close this mystery. Luckily, in true Lynchian fashion, this mystery's solution only opened the door for more mysteries and added much more to Twin Peaks' overall world and mythology.
This entire episode is filled to the brim with fun, fascinating, and freaky moments fueled by Lynch's visually unique vision. Lynch's passion for filmmaking helps improve upon Mark Frost's already exuberant script as he punctuates the episode with memorably surreal imagery and an overall stylistic makeover that delves into darkness both humorous and horrific. The final moments contain not only what may be the most brutal sequence in television history, but also a somber sequence at the roadhouse, a landscape now plagued by some unknown tragedy, where everyone's laid back attitudes have withered away into a disturbed state of some inexplicable sadness. Those shots of Bobby looking around, wearing an expression of hopeless weariness move me to tears almost every time I see them, and the odd elderly waiter, previously a purely comic character on the show, approaches a shocked and saddened Dale Cooper with some of the show's most strangely cryptic and memorable words:
"I'm so sorry."
