This was without a doubt the funniest horror movie I've ever seen!

It's only 28 mins but the story told isn't too bad at all. Plus, a "killer umbrella" sounds unique, the Japanese can really turn ANYTHING into a horror antagonist. Too bad that there isn't a "killer umbrella flying across the sky" scene like in one summary I've read XD that would've been hilarious
The length was also sufficient for this movie, 90 mins would've been too stretched out imo

Definitely recommended if you don't mind *very* cringe death scenes and shorter horror movies
