you should like this. "punch-drunk love" does for lonely guys what "Amelie" did for lonely gals. both films are about odd, introverted people. both try to show the world as seen by the protagonists: magical and dreamy for Amelie; sterile and nightmarish for Barry Eagan. both are charming and sweet love stories. and strangely, both involve the sex trade! each in its own odd way. pdl is a (slightly) funnier film, though.
each film also makes interesting use of a different spatial dimension. in A, the vertical dimension is very important - many things either fall (A's mother, the goldfish, etc) or are discovered on the ground (the treasure box, torn pictures, boyfriend, etc). in PDL, it's the dimension into the plane of the film that's important - think of the long driveway leading up Barry's shop, or the corridors in the apartment and hotel, or the aiport walkway, etc. it's no coincidence that Leana first emerges from the end of the long driveway, or that Barry runs through the the long apt corridors to steal his first kiss, or that the lovebirds first hold hands as they stroll through the winding halls in the hotel.
the screenplay was very well written, especially for Barry. the conversations were funny just because they are so accurate: this is just the way you'd imagine someone like Eagen would talk. hilarious.
a good film. well worth watching.
