Nocturne (2020) review

There's some intense sibling rivalry going on between twins Vi (Madison Iseman) and Juliet (Sydney Sweeney) at art school: Juliet finds the study book of a talented pianist who committed suicide and uses the information in it to take down her sister.  Like so many other failed "horror" films of late, Quirke uses the same old "long and slow" takes in order to try to create a sense of "uneasiness," but it just feels unnecessarily stretched out, and the "hallucinations" Juliet experiences are more (unintentionally) funny than ominous.  In order to qualify as "psychological horror," it might be a good idea to have a basic grasp of the field instead of watching Black Swan and trying for the same effect.
