Well, finally bought this from DVDSoon as it was going cheap and watched it this evening.
Have to say, I really enjoyed it. Much better than 'Kids'. The film was paced well and the characters were believable and realistic. However, the first 40 mins or so made me think that this was just a porn movie with a plot. There's minge everywhere

But that plot is there and so are the characters, and you realise after a while that it's all there for a reason. As Encaser says, it is hard to point a finger at who are the victims here, as all seem influenced by their peers and surroundings. So at the end of the film you're left feeling that all were victims in a way. The violence is uncomfortable and I did find myself wincing at some bits, but overall it was justifiable and I'm sure Larry Clark would be pleased with the effect on audiences.
The fact that 'Bully' is based on a true story makes it even more disturbing. (Some extra info is given in the post-credits text btw.)
Inmate numbers are given on the disk in the Special Features section, along with a website address for the
Florida Dept of Corrections, so you can read up more about the real characters involved (and see real photos). A nice touch as a special feature I thought

Looking at the photos, it's amazing how rough Lisa, Ali and Heather are in real life compared to their on-screen counterparts
It was a 7/10 for me

Now if they would just realise an anamorphic unrated version of 'Kids' ....
