I forgot about Il Grido. Very good. Of all of them, though, I think Cronaca di un amore is his most underrated. There's something really hypnotic about it. It feels like a silent movie. I do have a soft spot for Zabriskie Point, without necessarily thinking it's very good.
Kiss Me Deadly (7/10)
I like this, but not as much as most people I know. It's all a bit too clever, made by someone who looks like they've watched too many German Expressionist and Orson Welles movies for their own good. Bits of it are undeniably brilliant but the excessive visuals eventually threaten to capsize the whole thing.
