It's strange how people see things differently. It's possible the film doesn't resonate with your personality. I do recommend watching it carefully again if you've only seen it once.
You can see it as dragging or as character development and storytelling. Of course, you do have to appreciate the claustophobic and sinister atmosphere here. For me it's a rather lyrical ride but I must say; I've often noticed that opinions on this film differ widely.
But i'm certain of my opinion. I've seen it seven times. Still, I respect the fact that there are people who see it differently.
Didn't like Jackie brown bye the way.
