Yes, if like me, you see this film without knowing anything about its content and presentation, you should find it astonishing. As you can see from the plot summary in IMDb above, the story is a true one, in Ipswich in Britain, where five murders occurred not that many years ago. These events were then taken up by the National Theatre, and now as a film. There are a wide range of characters in the street (London Road) and they all have their own words used to make the dialogue. However, it is the presentation and delivery of the story that makes this film so riveting. My only reservations were the handling of two of the central characters which seemed a little far-fetched, but these are minor quibbles in a film which will be very differently delivered on the screen from what anyone would expect. Some of the imagery in the crowd scenes is especially noteworthy. Definitely recommended for art-house film fans, and the large crowd in Melbourne at the screening I attended seemed to be most impressed by its audacity.
