Uh, hello? Are you aware that it’s a movie? How is it that you can accept the existence of a fictional animal, but get pissed at the unscientific explanation of its diet, reproductive cycle, and aerodynamics?
I bet you’re one of those people who sat enthralled through ET and got pissed when they flew the bikes across the moon, aren’t you?
The only reason your intelligence is being insulted is that you evidently think far too much of it. And if your intelligence is so great then why don’t you have the sense not to take it so seriously?
