great movie, i loved it.
i can even forgive it the massive plot hole:
the microwave device?
how did it not fry every human being who came near it when it was turned on?
microwaves work by vibrating water molecules in your food quickly, this creates heat through friction = your food gets cooked.
your microwave doesn’t fry you cause its shielded so the microwaves can’t get out of the microwave.
if it was strong enough to vaporise water while in metal pipes, its strong enough to kill everyone in range…
