Lynch at his best will be surreal and confusing, making you wonder what you just watched, while still having an emotional impact.

Mulholland drive is a favorite because it balances the straightforward plot of the first half with the wtfness of the second half. If you couldn't stick with it because of the second half, try Blue Velvet, it's narrative doesn't unravel half way through. Just know that part of the fun of lynch is trying to make sense of what you just watched.

Lost highway was where I started. Completely blew me away. Surreal and confusing, but there is just enough there to sort of make sense and keep you thinking about it.

FWWM is amazing and was criminally underrated at the time it released, but it spoils the series.

Twin peaks is great, but if you bounce off it because of the intentionally goofy soap opera elements, there is a fan edit version called "northwest passage" which turns the first two seasons into a five hour movie focusing on the murder investigation, and its pretty well done.

Season 3 is a whole separate thing, and is fucking great. Just 18 hours of lynch doing his thing and pulling elements from his entire life's work.

Eraserhead is great, and is considered a classic "midnight movie" for a reason.

Elephant man and the straight story are the only conventional movies he's done, and both are worth watching.

His version of Dune is kind of a mess, but the aesthetics and weirdness of it all make it worthwhile. The new Dune is kind of blandly sterile in comparison.

Wild at heart is the only lynch movie I don't like. It has some great moments but overall it just leaves me cold.
