This Is Why I Don't Carry A Cellphone.

seems like a Taiwanese-Japanese collaboration, the 'ancient' part is not feudal Japan, it looks more like some fantasy ancient Chinese. The lead actress was heard speaking both Japanese and Mandarin (she played 2 roles). The lead actor is some Taiwanese idol, also co-starring Sammo Hung's son. Looks dated and silly.

If it came across my desk, I'd watch it. It's seems silly enough to be worth that. Would I seek it out? Probably not.

Hopping vampires! OMG, I'd mos def watch this :P

That looks quite entertaining. And the title has been permanently drilled into my brain.

okay, trying to find some small details to bump this one up...

Seems to feature the idea of Taiwanese living in Japan, the daughter having to return home for some reason... then the timeslip element comes in it seems... think this one has potential - looks very weird and the kind of thing people will react to quite well.

what is the last hip hop song played at the end of the trailer while the group of people are dancing?
