Your comment is precisely why I despise the film, not necessarily the film per say, but rather the praise that has followed. I found nothing intellectual about the dialogue, I found it plain. I enjoy plenty of low budget movies with simplistic scenes that intend to really challenge the viewer - I just did not simply see those scenes in the two films.
If you liked the sunset/sunrise movies I recommend: In the Bedroom - if you haven't seen it. I absolutely shutter at the very hint of the title, but I believe that you might enjoy it.
