"Gawi" (aka Nightmare/Scissors/Horror Game Movie) was Byeong-Ki Ahn's first horror film. It's a decent, if unoriginal attempt at horror, and is somewhat effective. Then again, this movie is chock-full of flaws.
First is the lack of coherent continuity. The movie confusingly switches from the past and present without warning, and has quite a few badly-placed flashback sequences. The next thing is the complete lack of originality. There is not one but TWO long-haired vengeful female ghosts, gory deaths reminiscent of every other slasher in the world, an ending clearly jacked from every other sequel-promising slasher. The last thing is how ineffective it is: yes, it is effective to a degree, but not as scary as it could have been. Having said all that, "Gawi" does have a few good twists along the way, and I must say, a fairly gripping mystery story going for it.
If you like slashers, or liked the director's later movie "Phone", this is recommended.
My rating: 6/10
