Buyer Beware looks like an amalgamation of horror tropes, however, unlike a parody\satire - this movie actually tries to make something out of these tropes. It doesn't have great CGI, or outstanding actors... or even particularly scary scenes. But, to me, it was still entertaining, I was interested in how it would all resolve, even if it was somewhat predictable. Probably most of all I liked the idea, enough to want to see a sequel, because the setting is there. It could easily rival current mainstream Hollywood jump-scare fests. Mainly because, unlike those jump-scare fests that have nothing in common, the idea about real-world hauntings and their... ehm... application - is something new.
Mostly we see one-off movies focused on a particular subject. And, as much as they try to franchise it - they end up one-off with only CGI to save them(and, sometimes, the actors). This budget picture doesn't need either. Sometimes you see a horror and it doesn't work out, because... it's just empty. But this movie has a setting, and I hope they'll build up on it. Don't watch it expecting to be scared, watch it to find an interesting take on the already over-used cliches.
