Negative reviews helped my perception

Rating: 8/10 (28 December 2018)

I went into this not expecting much. The negative reviews helped me to lower my expectations, which meant I was pleasantly surprised at how much I enjoyed it.
The storyline is in a similar vein to Stephen Kings novel 'Cell' -note I said 'similar', it is in no way the same. But the basic principle is there, except in this story, it's about what the individual sees. We never see what it is that causes the disturbing behaviour, which I note a lot of people have complained about. However, I think this would cheapen it-there is no feasible way to bring to the screen what this 'creature' is without turning the film into a tacky joke. Some things are best left to our imagination.
There's plenty of suspenseful-watch-through-your-fingers moments and you're never entirely sure what turn the plot is going to take next. Overall I very much enjoyed it, and I struggle to understand the negative reviews. But, each to their own
