Sorry for taking a while, but I have some thoughts on the film. It's now at least two weeks since I watched it so I'm rather relying on some iphone notes I made whilst watching, some of which mean more to me than others!
Like others, I found the look of the film interesting. Having seen Delicatessen and Mic Macs it's clear the filmmakers have a consistent colour pallet (lots of browns and greys), some consistent stylisation (like the buildings, one of which seemed identical to the Delicatessen apartment block), an enormous eye for detail (like a great painting) and some consistent method of zooms and pans.
Compared to Delicatessen, I thought this film really moved on in how its style mirrored its subject matter. With the children central to the film, there were several aspects I thought were evocative of a number of children's films and books: the rat catcher from Chitty Chitty Bang Bang, the cityscape was like the end rooftops in Mary Poppins, there's quite a lot of Oliver Twist in there, Crumb walking with the string is straight out of a fairytale and the brain even made his history into a fairytale when he told made the bald, evil guy cry. None of this detracted from the originality. Indeed, their style is so unique it's difficult for it ever to feel unoriginal. I thought the flea poison / music box control thing was bizarre but very original and funny.
I'm not sure quite what the significance but I've made a note that there seemed to be repeated portrayals of distress caused by physical experience, in shortness, in baldness, through the loss of an eye and (maybe stretching it a little), the twins.
I thought the filmmakers really succeeded with characterisation with Crumb. I felt a genuine connection there as a viewer. Whilst Perlman's character was weaker, the connection to Crumb was such that I found the scene of hugging and where he was her 'radiator' when sleeping on the dockside genuinely touching, and equally the violence he was made to use against her genuinely upsetting.
I was especially impressed by the 'butterfly effect' scene that ended in the prevention of Crumb's murder and the collapse of the dockside. I can't remember all the details now, but I've written down how a single teardrop affected a bird, which affected a dog, then a man, then a pigeon, causing a car to hit the fire hydrant and so on. Out of small things come big things? The chain of life is impossible to fathom? Out of sadness comes a positive?
In relation to the evil, bald guy I've written that his only happy dream is youth but even that dream brings fear and isolation. But only towards the end through weakness does he have any empathy.
Can't remember the context now, but I liked a quote, 'nothingness equals the infinite'.
And I laughed out loud when they were trying to row away from the rig at the end but had left the boat tied to it, and one of them shouted out: 'it's following us!'
Good film choice, I too would like this on blu.
