Three more for the list (which puts me at 179):
I wasn't looking forward to it, but STAGECOACH was a great experience. A little too much comic relief for my tastes, perhaps, and
but these are minor quibbles - I liked how the myriad characters developed as things progressed, and I was genuinely wrapped up with everything by the end. And having only seen the later John Wayne, the young John Wayne was a total revelation.
THE LADY EVE was my second screwball comedy in three days (the first was MY MAN GODFREY) and I continue to have reservations about the genre, most notably in the utter arbitrariness of the character developments. For me, the end didn't ring true at all. I don't want to be too negative, to be fair, as there's a LOT to recommend here, and I was definitely entertained.
L'AVVENTURA ... boy. I feel like I need to watch this with the commentary, and watch it again. Just listening to a couple minutes of the commentary made it clear I was missing tons of things that Antonioni was doing. A very striking film, and it's not one that I can say I loved off the boat, but it's one I'll definitely return to again.
*EDIT* - Just noticed that I had forgotten to count TREASURE OF THE SIERRA MADRE, which puts me squarely at 180. And one more discovery - A DAY AT THE COUNTRY is originally titled PARTIE DE CAMPAGNE, which I've seen as well, so 181.
