The storyline was good too, it had plenty of twists and turns throughout keeping the viewer guessing, and managed to avoid predictability (unlike 'Hollywood-big-budget' films) and really pulls the viewer in.
The cinematography really stands out, clever shots, great colour use in some scenes too and really brings a different kind of life to the film. Most notably for me was the alleyway beating scene, the dark plot twist/events of that scene are contrasted by the brightness and the popping colours. Definitely interesting visually as well.
Overall, certainly well worth the watch.
