First off I must state I have not seen the first part of Kuntinalak. This really subtracts from the experience, as despite my best intentions I was unable to fully understand this movie and put the pieces together to comprehend the script. It seems too much of the puzzle revolves around events in the first part. This has substantially lowered my score of the movie.
Other than that is even a top notch Indonesian horror flick and an above average Asian ghost story. The cinematography is quite interesting adding suspense, horror and eeriness throughout. The 'monsters' in the movie are very nicely done and sufficiently creepy to make you cringe at least several times during the movie.
Once more I find acting and some of the directing not up to par with the remainder of the movie. Most actors do an OK job, but that still does not change the fact that it is full of awkward moments. Similarly directing is mostly great, but there is a couple of corny or badly done scenes which stick out like a thorn from this movie.
Overall a solid production and despite its fault I must say that I haven't been as freaked out by a movie since... Angkerbatu... Also an Indonesian horror movie.
