All over the place

Rating: 5/10 (7 April 2019)

This is a movie of two halves. The first half is a pretty decent suspense thriller, in a confined environment, where you don't really know what's going on and then, just when you think it's ending, there's a whole other half in a different setting that's significantly less good where they make the fatal mistake of trying to actually explain the highly unlikely goings on.
As a result it feels like the film has about 6 acts instead of the usual 3, and by the time it ends you don't really care anymore as instead of being a tightly plotted thrill ride, the writers continue to throw all sorts of ideas at you in the hope that some of them will work, each less well thought out than the last.
If they stuck to just the initial setting and maintained some mystery it could have been awesome, but as it is it just goes on too long and loses focus at around the half way point.
