Watched this again the other day after many years....
After watching Spring Breakers I had to remind myself that Korine really is a good film maker so I did a re-watch of Gummo.
Not much a point to make other than to say that this was even better the second time through. It does take a certain skill to make the viewer feel emotions and even some sympathy for cat killing sociopaths but that is exactly what this movie does.
The worst offense that Spring Breakers had on my senses was that it was completely boring and sophomoric at best. I didn't know who any of the actors were, except Franco, so them being in it did nothing for me. Any four random hot girls would have had the same minimal impact.
Gummo on the other hand had soul and was quite carefully crafted. I am a cat owner who watched this movie with my cat as nobody else was all that interested when I told them about the graphic nature of the violence towards felines. None of the violence was real so it didn't bother me in the least.
