To sum it up, I would say that, just like in the previous movie:
- The main character, the detective, well... she doesn't seem to do all that much: she just basically keeps on wandering without doing any real police work. Work that she lets her colleagues do while she keeps herself busy by making Skype calls with her "FBI friend", breast-feeding and listening to some "sensations" of hers.
- The "witch/black magic" plot it's not only cliched but "ominously" ridiculous, and of course had to have something to do with the crazy mother of the detective (you'll see that coming if you have seen the previous movie...)
This is a truncated movie with no real ending. It's a frustrating feature because of its sometimes lackluster plot and frequent plot holes and unfinished narrative. Also because of the bad acting and the almost total absence of suspense (the only exception to this being the last few minutes).
So, if you wanna see an unfinished and convoluted thriller that'll leave you lingering 'till the next movie comes out well, help yourself. You'll be well served. But, on the other hand, if you like well-rounded thrillers that pack real surprises and that are able to connect all the dots together nicely, that are able to wrap the all narrative up in a satisfying and logical way well, give this movie a pass.
