Can someone explain this?

So, after stopping halfway through the Justice League trailer, I have to ask: What's the deal with DC and their unwillingness to have accurate portrayal of their characters? I mean look at Marvel, aside from Nick Fury, all the characters have been more or less accurate appearances of the way they look in the comics. (Movies, don't know about the tv series), but then DC goes off the deep end for some reason, with some subtle dislike for blond/blue-eyed characters?

Case-in-point: Look at the DC Cinema Universe's Aquaman:

Now look at the comic:

Then we have Barry Allen, which is a mindblowing 'f-u' to the readers if I ever saw one:

Seriously, how does blond, blue eyed Barry Allen not transfer to the movie universe? It's not just the movie, but the tv show as well:

Am I the only one that wants to see an accurate depiction of the characters I'm reading?

Special bonuses are:

But yes, I'm serious. I feel like I'm the only reader that's continuously blown away by how well Marvel Studios depicts their MCU characters in relation to the comics, but continuously cringe at how badly DC is portraying their characters. Can someone please tell me what the deal is? DC makes the trinity look just like the comic, but fail at the rest of the Justice League (aside from Cyborg, I guess)? If this is the wrong section, then a mod can kindly move this thread. Also, I still won't forgive DC for the travesty that is Man of Steel.

Excuse the thread alignments. I had it set well enough, but seems the forum took away the styling.

Because they think who plays the character is better than who entirely looks like the character, and for the most part, they've nailed casting decisions.

Lex is the only one they've failed imo.
