A classic mindbender plus probably one of the best starting points for digging deeper into the great line of films directed by David Lynch. One of the movies where you actually might need to read through a "Movie explained" -article somewhere on the net after the movie, yeah, even if you consider yourself above average smart.
I'm generally a Lynch fan. This is polarizing but engrossing. What plot there is begins with a beautiful woman with a bag full of cash and a case of amnesia. The places Lynch takes you from there visually depicts dread, insecurity, lust, and evil.
Convoluted plot that fits together for the 1st half, then in true Lynchian style, paradoxes occur... The plot isn't to meant to fit together with a satisfying click (that's his intention, for reasons unknown), though really atmospheric and engaging
