I apologise as this probably breaks rule 4, but I recently saw Tarkovsky's Nostalghia and it opened my eyes to film as a true artistic medium, and I want to ask for suggestions that are of a similar ilk.

And when I say a similar ilk I do not mean similar in tone or style or anything like that, I simply mean films that you watch that you do not feel are worth talking about because trying to write or talk about them inherently and immediately belittles them (I get that may be slightly hyperbolic, but I hope it conveys what I'm saying). I just want to watch films that you can only experience, and they may be somewhat enhanced by certain analyses or whatever, but fundamentally they are just breathtaking experiences.
