for NEON, i think it would go like this...
1. TWIN PEAKS: PILOT - EPISODE 14 (i know it doesnt really count, but it's by far my favorite lynch, especially his episodes.)
2. BLUE VELVET
3. MULHOLLAND DRIVE
4. ERASERHEAD
5. ELEPHANT MAN
6. THE STRAIGHT STORY
7. LOST HIGHWAY
8. WILD AT HEART
9. FIRE WALK WITH ME
10. DUNE
but honestly, i would have to re-watch them all again to really have an opinion since i saw the first handful pre-Twin Peaks and didnt really 'get' him yet. so that means WAH, EM, BV, even MD all need to be watched again.
