I won't add too much to the reviews already here except to say that I agree with all those giving this film 4 or 5 stars. It is not everyone who can remember the intensity of teenage infatuation. I think we largely forget (or want to forget) how intense our early loves were. Those who wrote, produced and directed this film can still obviously remember such feelings.
Your heart goes out to Pim really. He is living in one world and the object of his desires is living in another but parallel one. I felt really really sorry for him when he went to give his special drawing of his love with a token symbol only to be so devestated by what he saw through the window. The mother is (unfortunately) played very well. Too well possibly. She is not a bad woman. She had dreams of travelling Europe (you should see her eyes light up thinking about Capri) playing the accordian in a gypsy band. They she got pregnant and all that came to a halt. Not that she didn't try to recapture those glory days while Pim was just left with a tin of sardines. She doesn't neglect him as such but just doesn't understand him. I liked the part where the gypsy comes to rent the room and they are going 'to have dessert'. 'There's dessert?' Pim asked. The mother's face could kill at that point. As if they never had dessert. Which I suspect is true.
It's a lovely film. Well deserving of 5 stars. The scenary is beautifully shot too. See the moonlight on the sand - like stars in the sky. Wonderful.
