For the constant twists and turns, it's surprising that this drags out the way it does until maybe 20mins before the ending. I've come to admire Joko Anwar's work, but unfortunately Modus Anomali is not what I have come to expect from him. Could benefit from a tighter direction, better editing and better acting. Maybe it would work as a short film.
Would've jumped right into the plot holes if I didn't know beforehand that it's intentional. The use of English's more than a tad distracting, acting offers nothing much to compliment/nothing to really sympathize about. Bits and pieces make it bearable e.g. the cinematography, copious amount of blood, the score. Can't shake off the feeling that maybe this should've been shorter and on Vimeo.
The camerawork's able to instill anxiety in any viewer, also helped by the eerie score. First 50 minutes still felt too long and they fell flat, but it's all made up (saved?) by the bold third act, brilliant long shots, the [a fitting adjective here] 'twist' and some visual brilliance. Plot holes are excusable (I guess).
