Best Blu Rays I have seen:
One-Eyed Jacks (Criterion)
Spartacus (2014 remaster)
Lawrence of Arabia (Sony)
Persona (Criterion - all of their Bergman films are jawdropping, brings new life into the close-ups) Many of the early Bond movies look fabulous, all were 4K restored
The Quiet Man (Olive)
Shane (Warner/Masters of Cinema UK)
Sweet Smell of Success (Criterion/Arrow - the blacks are soooo inky!)
Stalker (the new upcoming Criterion version, debuting July '17)
She Wore a Yellow Ribbon (Warner Bros.)
The Tree of Life (Fox)
Mulholland Drive (Studio Canal 2017 4K remaster).
The Searchers looks great as well, even though it was one of the first Blu Ray titles released in 2006. Would look even better today though with a 4K scan. Many of the other VistaVision movies look terrific like Vertigo and NBNW.
