This is either the worst movie I've ever seen, or the second. Another example of showing the only portions that appear to be briefly-interesting in the trailer, then delivering a steaming pile of disappointing and empty (feces).
From the moronic dialogue to the overacting and comical stereotypes to paint the "goods" and the "bads" there is no room for nuance, creativity, abstract thought, a chance for hasbeen/unknown actors trying to get a gig to tell a story worth listening to - nothing.
I've wasted my time doing all sorts of things in life, and this is undoubtedly one of the worst.
If you happen to read this, director/writer Alex Garland: you beyond suck. Pursue anything else in life to retain any dignity like working at a Waffle House, prison janitor, even doing Sign Language for the blind would serve a more meaningful purpose than what you have plopped on the screen.
A terrible shameful and a waste: time, "talent" and attention of anyone else having suffered through this garbage. Bad day to you.
