Saw this at a preview screening today. I have never seen the Director's most famous film, Romper Stomper, and know it only by reputation. My guess is this very graphic and bloody version will satisfy his fans and many others. Doubt I would recommend it to anyone who was unfamiliar with the play but, taken simply as a film, I believe it is excellent. Superb cinematography and great sound track back up a 'reading' of the play that seems to me to have real integrity.
I note the current average rating on IMDb is a fraction over 3/10. Assuming the vast bulk of those are votes by the illiterate and inexperienced voters with a mental age of 12 who usually bulk out the meter, that probably bodes well for what is quite an exceptional film. If you don't know the play, for god's sake read it and don't send your ignorant comments to this forum.
