The only people who consider these 'plot holes' are twelve year olds on reddit. That's why they're so easily explained. Real plot holes are like how space ships fall down in Star Wars, or how George Clooney floats away in Gravity. I can't think of others right now, but what I definitely never thought was that any of these were a plot hole.

#8 OK, but zookeeper are pets of lions and bears, so NO they will NOT eat or attack them willy nilly anyway. Animals aren't stupid and don't attack everything just because they are a little hungry.

#11 Actually DeLorean was a scam artist who embezzled the finds of an entire nation and no one wanted his cars.
