Unsettling?

Did anyone at any point feel unsettled or mildly creeped out by this film? The extended stalking scene, especially when the protagonist is staring at the woman in her apartment, and monomaniacally following her through the city, including back alleys felt slightly weird. The imagery of the scrawled graffiti, the lack of speech and the extended fixed shots throughout added to the eerie tone. I only felt this briefly, but I'm sure that with some re-editing and inclusion of creepy music the film could be made into something different.

Anyone else?
