No pun intended - and not even close to the "not without my daughter" I am riffing off. This is quite different from that - I mean this is a horror movie, so you got a major difference already! That said - let's focus on what the movie is actually about: family, aging, death and legacy. The movie made me think - about a possible future about the unstoppable ... row of time.
Not really a feel good sentimentality I am putting out there. But it is what it is - which is also true about the story the movie offers - as in predictable! I don't even think you have to have watched many movies to get where this is going.
The characters seem to need a bit longer to get the obvious I reckon. One of the actors doing double duty (well actually the mother in a way too, but differently, as in being only one character) ... and the one character he is playing is quite out there .... the main characters make fun of him - but not sure that is enough to make away the cringe you may feel.
A few good shockers, a few completely unnecessary scenes (a signing that really has no merit and no excuse being in the movie - unless there is some deleted footage that would tie or explain its existence) ... overall it does have the right themes and might give you a horrible feeling ... just maybe not the one you were looking for ...
