I would just like to point out: there are no pictures of Wonder Woman.
Wonder Woman is a drawn fictional character who for 70 some years has been drawn by many many different people and has looked different in those pictures over those 70 plus years.
So, again, there are no pictures of Wonder Woman. Just lines on a page representing a human being. An almost impossible human being.
Thats just stupid. Yes, she's not a real person. But, by your logic, anyone can be cast as any fictional character, at least from comics, because they don't actually exist.
Richie Rich Remake? Call Vin Diesel. Live action Archie? Anthony Hopkins can obviously play the title character. Need a Zatanna? Well, then look no farther than Betty White.
Not counting elseworlds stories or other people that have used the name, the normal Wonder Woman (Diana Prince, daughter of Hipployta) has stayed consistent since she was created. So have most superheros. Almost every major superhero has basic traits that have been consistent for basically their whole existence, with things like faces changing by artist but still recognizable as the characters regardless.
Wonder Woman's traits:
Female (obviously)
Caucasian or possibly greek (I think it still counts as Caucasian anyway, but being from an ancient greek like civilization it could be specifically used as a basis), but generally still Caucasian looking. She usually looks like, appearance wise, she could have come from America, canada, britain, or similar countires, although this can be tweaked a bit and it wouldn't matter.
Strong and athletic, but not to a female body builder level (not counting bad anatomy in some eras, like the 90s). Her more...feminine attributes can vary, and to me it doesn't particularly matter. As a general rule, in more modern times she's usually only beaten by Power Girl in that category, although that literally doesn't matter at all to me for casting or how she's drawn.
Black Hair
height varies, from around 5'10 with a clueless artist to about 7 feet tall in a few extreme cases. As a good median, she's usually taller than batman but shorter than (or equal to) Superman, so about 6'2'' to 6'4'' or
maybe 6'5'' on the outside.
Thats been fairly consistent since she's been around, although her creepy creator probably made her shorter and smaller than normal. But, I'd say by the Silver age and later she's generally been as I described her, and thats how I judge casting choices by. You may find outliers and elseworlds stories, but I don't think you'll find many comics set in any era's main continuity (outside of, again, possibly her weird creators time and the rest of the Golden age) that stray far from those traits. So, fictional or not, she has consistency.
Gadot doesn't match that, and the ways she really doesn't match (height and build) aren't things I see her adding to a significant degree.
