I would say this film definitly ranks in my top 3 any day of the week. What I love so much about Jarmusch's films is how unconventional they are, not just for the sake of being unconventional, but for the sake of not sacrificing one bit of artistic integrity for mass appeal. He's not afraid to go just at the pace he needs to and not a frame faster for the sake of marketting the film, even though most viewers would say it's "too slow".
I remember the first time I tried to watch the film I gave up about half way through, mostly because I was in a room full of 5-10 loud, drunk people, myself included, which is not exactly the best way to watch this film. I would say since then (a little over a year ago) I have seen it at least 20 times. I absolutely love this film, and it's that rare kind of film that if I have the time, I'm almost always in the mood too watch, and I never find that it gets old or that I get tired of it, in fact, I love it more with every viewing and it seems to take my appreciation of it to a new level every time I watch.
Absolute brilliance. Unfortunately, I think with most of today's audience the way they are (used to artificially, overly fast paced, meaningless, greed inspired, sorry excuses for films) films like this will become more and more rare, until the film industry finally has another sort of 'internal revolution'. Thank god for films like this is.
