Lacks substance

Rating: 4/10 (24 December 2018)

This movie has a decent premise, kinda similar to "the happening"s , but feels too artificial and unconvincing.
It's ok if a movie doesn't explain everything and leaves a few questions unanswered. But this movie doesn't care to explain anything, nor even develops its characters.
I watched It til the end only because of Sandra Bullock (which probably costed 70% of the film's budget) and cause I had enough beer.
