Literally any character in this could've died and I wouldn't have cared. This does a poor job at giving anybody any redeeming qualities, and it lacks a sufficient number of bodies to drop to make it into a scary, slasher-thriller.
'The Owners' relies on shock value to keep it's audience engaged and to be honest, it just isn't all that shocking. We've seen a lot of this stuff in better, more recent horror movies (like 'Don't Breathe'), and this fails to subvert the genre the way it wants to.
The cast do a great job at making themselves hateable, which I think was the point, but it certainly doesn't make for a good movie if it is. At multiple intervals I was waiting for something, I don't know, redemptive to happen, and it never comes; these people just suck, and that's fine, but the kills, and the justice for that matter, are not served up well enough or consistently enough.
