Ingmar Bergman's Persona comes to mind. No doubt that it's well shot, acted, thought out, and effective, but it all comes down to a person experiencing someone manipulate her by not speaking-with the occasionally trippy sequence or snuff imagery to mix it all up. I wouldn't accuse it of being shallow or unimportant, but I would say its status as a "great movie" overshadows its viewing experience, if that makes any sense. It's depressing, but it lacks an emotional catharsis. So it feels like looking out the window during a rainy day. Just kind of dull and mysteriously bleak-rather than having satisfying character motivations. Maybe I should have posted to the UnpopularOpinion thread, but I think this could deserve its own thread.
