This is the first time I have watched a show and loved it, but it has no solution to the problem! I want to know where did they come from anyway! I may have missed something from the beginning of this 'Day One (2024)!
Since those creatures are afraid of water, why not create a storm/hurricane/heavy rain to wash them away in the end, if they tried to get into the boat, people should shoot them, but leave one alive to eat/attack the star of the show?!! Oh, one other point, if the place is so DESTROYED, how did they find a well-baked PIZZA!!
