I'd much rather watch something with less resolution and a smooth/softer picture than something with more resolution, but with a jittery and choppy picture that ruins the experience.
No one in their right mind would ride on a buggy driven by Klaus Kinski.
They inserted black frames every 10-20 frames, accidently, that's why. Throw the disc away, pure garbage. Get a Region free player if you can and buy the UK disc. Way better + even more restored. Eureka cleaned up a few more dust dots and scratches.
Yes! Eureka's blu ray is the ONLY way to see this masterpiece! Kino seems to screw up more silent films with framing, frame rates. Eureka has proven they are the best when it comes to FW Murnau silent films (their Sunrise and City Girl are phenominal on blu ray!).
