I dropped this after about 40 minutes. At first the story has trouble deciding if it's a thriller or old age drama. The lack of chemistry between the leads is distracting. You don't get the feel they're newly weds, not even that they share a history.
Then, while already under suspicion for murder by circumstance, heavily in debt on paper and having stolen a bunch of cash that apparently didn't get noticed by the police investigation, the smarter of the two, without hesitation, offers to pay for the cremation, when the nice police lady brings it up.
If people really are that stupid, they deserve every bad thing that's coming to them, so I'm no longer interested on what comes and how it affects them. Sorry for the actors, I think you tried, but this story just doesn't work.
