Plot question... ***spoiler****
Why could the alien not suck up OJ under the bleechers? We are told it sucked up the whole audience there and see it attack OJ when he is hiding under the bleechers there later. It cuts away and OJ just wakes up afterwards. He must have passed out but otherwise he is OK.
Jean Jacket later on goes over to the house and is able to suck Keke Palmer through the roof with no problem.
Why? How? Mistake in writing?
