Other mistake: When the Amazons interrogate Steve they don't know the meaning of the word "crap" yet they know one of the definitions of the word "rack."
Suggested correction: Just because they understand some slang, doesn't mean they should understand all slang.
Well if they're an ancient race then how do they know of the use of the word rack regarding female anatomy? One of them went out into the modern world and learned this? Hera tell them this? Maybe they got internet or a modern dictionary?
Well obviously they know stuff about the modern world. Diana could speak Dutch fluently, not Old Dutch either, but modern Dutch. So they do get information or else she wouldn't have known that. This would include slang.
Other mistake: When 1 strikes off 2 (I think) from the calendar we can see that 1 is Wednesday, 2 is Thursday, 3 is Friday and that 4 is Saturday but 5 is Monday; meaning that Sunday has no date.
Other mistake: In the end credits, BASSES is misspelled as BASESS. (01:45:10)
