No pun intended - I have been to a few BnBs (there is one particular App that is in the air, but I will not mention it - quite certain there are more out there too) ... I never had a host as weird as that. Most were quite friendly - I have to admit, I do not know how I would have reacted. Ones own reaction informs (sometimes) what response one might be getting.
That all said, the Host (the actress) is really good ... it's a fine line she has to walk. Not to mention make it obvious but maybe not too obvious where this may lead ... now is there a twist here? I think there is, but you'll be the judge of that. Some nice touches (of phones, so no pun intended) included ... maybe more of a thriller than a horror movie ... still quite a decent one! Script is ok and the acting is good too. Seem worse shorts and movies for sure.
