FYI, if you can’t appreciate Surrealist filmmaking, you’re not going to be able to appreciate more than a handful of Lynch’s films. A Straight Story, The Elephant Man, and Blue Velvet are his most accessible, general audience-friendly films.
While I love Lynch, Mulholland Drive has always left me cold. It started life as a pilot for a TV series until plans for the series fell through, leaving Lynch to reconfigure it into a feature film, and I think it shows, with subplots that you could imagine gradually unfolding across multiple episodes just going nowhere in the final product.
