This is the second Rivette movie i watch, previous one was "La Belle Noiseuse". LBN is a better movie. PARIS BELONG TO US is a very strange movie but that's something everyone can guess just reading the synopsis and the plot. One can say there are political undertones here or a "Lynchian" vibe, even Kafkaesque. Whereas i don't necessarily disagree, i would say that this is not that political/cryptic/nightmarish. It's more drama than mystery and most of the questions were answered in the ending, even though the answers are not so satisfying.
In any case, i liked it a lot. Pace is very good for a 140 minutes French art movie of the 60's. It's interesting, it made me invest and i was curious to see where it goes. Great as a time capsule, Paris was wonderful. Actors are great. This is one of the movies that you should watch a second time for understanding it completely. I won't though. It's good but it is not THAT good. Pace was good as i said but it should have been at least 10-15 minutes shorter. For a 140 minutes movie, it should have been more intriguing to call it a great movie. And the ending was probably clever but i didn't like it, so much for nothing.
But there was some brilliant dialogue here. Way too cynical for its time of course. I think this is a timeless movie, hasn't aged a bit. Less obscure than it seems. If this description made you curious too, watch it, you won't be disappointed.
