Here's the main issue with complaining about her look or any female casting simply on the basis of their bodies: it's stupid.
I had this discussion with my homie the other day about Ben as batman. Now as much as I love this dude and he's basically my brother, he's not that bright when it comes to the word "adaptation" To him, Ben was too young to play batman in batman v superman because he couldn't wrap his head around the idea that they weren't doing a straight translation of the dark knight returns. And even with that said, you'd have to cast a guy around Clint Eastwood's age and a guy that age more than likely can't do the physical stuff required to be batman in a major motion picture.
Comic book characters, especially women, aren't always drawn to be realistic. Pick up a book from the 90s and tell me on average how many women look like that. So the idea that Wonder Woman needs to match a certain male fantasy just isn't in the cards. Whether it's bigger breasts or a bigger ass or a smaller waist.
Now for the cats saying she should be a ms universe type, you're forgetting that she does have an alter ego and still needs to walk around as Diana Prince without drawing attention to herself or looking like she can kick your ass. So if she's running the streets looking like Arnold Jr. then that goes out of the door. Also you want someone who has at least some acting experience. Asking for someone with no experience to play the part all because they look the part is the same as saying triple H should be Thor because he looks like he does and had long blonde hair
