One star because the ending was absolutely awful. I was hoping the leader of the rebels would takeover the train and put the people partying in the back or just work out a system where the young and able bodied take turns doing the work. Control the population by limiting babies per couple. Something. Instead they blow up the train and kill everyone. -10/10
The dumbest part was the shooting across trains. Even an expert marksman would have to do some calculations before coming even close to landing those shots. Complete waste of ammo.
