This is such a bizarre film, even by Lynch's typical standards.
It's clearly the makings of someone out of his comfort zone tasked to adapt a source material nobody outside of small group underground Sci-Fi/Fantasy fans to hop on the "Star Wars" band wagon, but god damn does it try.
It's brimming with effort and ambition in terms of visual and narrative scale and man, even at it's worst points (like the bizarre pacing towards the half way point), it's still an incredibly fun and interesting to film to watch unfold, especially after a second viewing knowing what's gonna happen and have a better grasp on it. And for clearly being out of his comfort zone, Lynch really does a great job of directing action sequences and these big scale sets.
Plus, how can you really not love a movie that features a soundtrack by Toto and Kyle Maclachlan riding a giant worm?
