I was done after kids (without seatbelts) survive a 100ft + cliff top bus crash (ignoring safeguarding of only one supervising adult), a kid finding petrol (it was a diesel bus), a mum stealing a vehicle from another family, a solider who points his weapon at everything that moves, a Japanese girl devoid of any spatial awareness. Such poor research and plot.
Ps. It’s nothing to do with aliens.
Save yourself and watch paint dry.
