The premise of Haunted Dormitory - Marionette Teacher is initially interesting, but ultimately let down by shortcomings in its construction, uneven narrative progression, and plot points that don’t quite add up. The horror elements feel ineffective, the performances are not particularly memorable, and some choices made by the characters seem hard to justify. As a result, watching it proved more irritating than scary. Although it might still generate some interest, there's nothing about it that would make me want to see it again.
