In my continuing quest to remind you that your concept of “realistic” in fiction is based on a flawed definition, Cracked’s “photoplasty” contributors found 23 flaws in fictional technology that if fixed wouldn’t have looked as good.. Although to be honest a least a couple of those were actually given explanations, like Wonder Woman’s invisible jet being mentally controlled, and the Millennium Falcon I believe has VTOL style “lifters”. But would you WANT the Terminator to look like this guy?
Not as cool as Arnold, is it?
