This is elder abuse.
I hope that, when I’m old enough to be in the target market for movies like this, they make good movies. They hire a cast of stars that would remind all these old timers of some great films, and they make this?
I am aware that part of the problem with this sappy, no-consequence, low-stakes murder mystery is the source material. But there are ways to do this in an interesting fashion. Do a spoof of a good spy thriller! Helen Mirren’s character is retired MI6. Play it up. Add a bit of tension; it won’t hurt anybody. Add a little bit of grit and texture to the frame; a little film grain goes a long way to making this look less like a bad “Shot on iPhone” ad.
In other words, make something you wouldn’t be embarrassed to show your grandkids.
But this is forgettable, and a wasted opportunity. The worst kind of cinema is the kind that rejects everything interesting about the art form in the pursuit of safety.
