Polaroid the 2017 feature film is not related to the
Polaroid 2017 short film but they do both have the same basic premise... and old instant film camera is found, you take pictures with it, the pictures reveal things you really don't want to see, and then bad things happen.
Polaroid the feature film is produced by the same team that did US versions of The Ring and The Grudge. There really isn't anything new to be found... bunch of high school kids, loners, cameras, blood, mayhem, and demons. It seems to take bits & pieces from other films, notably
The Ring and
Final Destination, and wraps it up with a new cover. Instead of watching a video, your picture is taken. Instead of being unable to avoid fate by dying in an accident you can't avoid dying by a demon after having your picture being taken.
On a different note... if you're going to use a camera as the main item of a film then at least get the usage of right. The flash being shown in the trailer is so bright it makes it look like somebody is turning on an outdoor floodlight used for spotting enemy aircraft or signalling for Batman. And the resulting pictures? So underdeveloped it looks like no flash at all was used. The real kicker? The camera model shown doesn't even have a flash; it would've used a disposable flash bar inserted into a slot.
Personally I think they went in the wrong direction. Instead of the usual high school kids fighting evil they could've gone the route of
Death Note -- take a picture of somebody and that person dies. Or maybe add a Jinn (genie) twist to it... the person in the picture dies but so does somebody else who has nothing to do with it other than knowing you and the 'demon' is the Jinn.
