Phim này không nổi lắm, chắc ít người xem nên cứ để tag spoil thôi
[spoil]phim này ý tưởng chất thật, xem mà cứ đến đoạn đám văn phòng lại thấy buồn cười

Mà có cái lỗi là phòng điều khiển sao chả đứa nào canh hết, chắc tại chưa đứa nào thoát nên lơ là ko canh phòng đó...
Điểm danh sơ đám quái thì có: Zombies, Người dơi, Ma đầu cưa (nhái ma đầu đinh trong hellraiser), Ma búp bê, hổ mang khổng lồ, hồn ma, tiên cá (xấu hoắc), con bé mồm to múa bale thì ko biết là nhái theo cái gì...[/spoil]
Về mấy con quái trong phim
