I was the 1000th person to rate the film, so I see it fair that I also throw up a review. Firstly, you need to know that this film is not for everyone. Absolutely not! Don't be lured in by Tom Hardy or Olivia Colman. You should instead be lured in by the unique take on film genre and a much more 'abstract' method of telling a story.
This is a musical about a series of five horrible murders that took place on London Road. Every lyric, however, is also taken verbatim from an interview conducted with real people and you therefore get some very genuine-feeling phrases being turned into musical numbers.
This all very weird, but the chilling melodies and rhythms as well as the intense and gritty way it is sung is frightening and works wonders. The acting is also very strong, but the intense use of color (or lack thereof) in the production and costume design is what really sells the songs and thereby the film.
The story is not too captivating, and there are times when a musical motif is used a dozen times too many, but this film is definitely worth checking out if you are in the mood for watching something extremely different and bizarre.
