A supernatural thriller with a harder edge than most Thai fantasy fare, “Alone” finds co-helmers Parkpoom Wongpoom and Banjong Pisanthanakun flying at a lower altitude than with their more inventive 2004 debut “Shutter,” a local B.O. smash. Tale of a Siamese twin contending with the ghostly appearance of her vengeful dead sister provides its fair share of chills, but is woven from very familiar fabric. A strong performer locally, spooker has snared distribution in several regional markets and will travel even further on ancillary.
Recalled from Seoul by her mother’s sudden illness, 30-ish Pim (Masha Vadhanapanich) starts seeing dead sister Ploy at the family mansion soon after arriving with supportive b.f. Wee (Witthaya Wasukraipaisam). Between shocks using bathtubs and mirrors to good effect, sepia-toned flashbacks show the siblings were as close emotionally as they were physically until teenage rivalry for Wee prompted a tragic separation. Sturdily performed by pop star-turned-thesp Vadhanapanich (debuting), and energized by a phantom who looks and acts more like the extra-cranky ghouls found in contempo Japanese and Korean horror, pic ultimately hasn’t the story smarts to pay off as more than a competent genre offering. Tech work is pro.
