I gave it one star just for trying

Rating: 1/10 (25 September 2019)

I don't want to give anything away since it isn't fair to those who haven't seen the film. However, all in all it's a waste of time, energy money talent.
However will comment on the script
it's a dud that appears to be very clever, but it's a dud
acting - well Michael Douglas isn't an. actor's actor because he always plays the same part - you know - that great comment - we need someone whose like Michael Douglas - you know - gritty, nasty, unhappy, full of himself, not really interesting but sells enough tickets at the box office to make it worth his while.
Rest of the cast is pretty good - they do their best - but really even with the twists and turns the outcome is almost predictable but ridiculous -
A waste of time and money and energy and talent.
It isn't a brain teaser - although it appears to be that, and it tries to be intelligent but misses the mark.
