Unbelievable setting (empty hotel with only a handful few staff) which is kind of excused in the end (I'd guess technical limitation lays out the plot). Very slow plot build up. Could've made an interesting horror suspense (almost no jumpscare) but the execution is pretty poor. Very bad narrative style (everything has to be said out loud by the characters). Overall poor acting. Decent CGI for Indonesian film. There isn't much to be watched aside from seeing pretty girls in sexy maid outfit, especially Shandy Aulia who got some good shots. Unlike most Indonesian horror, they don't really sell the sexiness, but somehow it's the most noticeable in this long 2 hours film.
